Small packaging tweaks:

These were suggested by paultag@debian.org

1. debian/changelog just has the one entry, to indicate what has changed from
the perspective of a user of this package. The old changes in that file have
never been uploaded to Debian

2. Uploading to unstable instead of experimental

3. Bumped up debhelper compat to 9

4. Removed DM-Upload-Allowed

5. Minor standards bump

-=head1 NAME
-
-feedgnuplot - Pipe-oriented frontend to Gnuplot
-
-=head1 SYNOPSIS
-
-Simple plotting of stored data:
-
- $ seq 5 | awk '{print 2*$1, $1*$1}'
- 2 1
- 4 4
- 6 9
- 8 16
- 10 25
-
- $ seq 5 | awk '{print 2*$1, $1*$1}' |
-   feedgnuplot --lines --points --legend 0 "data 0" --title "Test plot" --y2 1
-
-Simple real-time plotting example: plot how much data is received on the wlan0
-network interface in bytes/second (uses bash, awk and Linux):
-
- $ while true; do sleep 1; cat /proc/net/dev; done |
-   gawk '/wlan0/ {if(b) {print $2-b; fflush()} b=$2}' |
-   feedgnuplot --lines --stream --xlen 10 --ylabel 'Bytes/sec' --xlabel seconds
-
-=head1 DESCRIPTION
-
-This is a flexible, command-line-oriented frontend to Gnuplot. It creates
-plots from data coming in on STDIN or given in a filename passed on the
-commandline. Various data representations are supported, as is hardcopy
-output and streaming display of live data. A simple example:
-
- $ seq 5 | awk '{print 2*$1, $1*$1}' | feedgnuplot
-
-You should see a plot with two curves. The C<awk> command generates some data to
-plot and the C<feedgnuplot> reads it in from STDIN and generates the plot. The
-C<awk> invocation is just an example; more interesting things would be plotted
-in normal usage. No commandline-options are required for the most basic
-plotting. Input parsing is flexible; every line need not have the same number of
-points. New curves will be created as needed.
-
-The most commonly used functionality of gnuplot is supported directly by the
-script. Anything not directly supported can still be done with the
-C<--extracmds> and C<--curvestyle> options. Arbitrary gnuplot commands can be
-passed in with C<--extracmds>. For example, to turn off the grid, pass in
-C<--extracmds 'unset grid'>. As many of these options as needed can be passed
-in. To add arbitrary curve styles, use C<--curvestyle curveID extrastyle>. Pass
-these more than once to affect more than one curve. To apply an extra style to
-I<all> the curves, pass in C<--curvestyleall extrastyle>.
-
-=head2 Data formats
-
-By default, each value present in the incoming data represents a distinct data
-point, as demonstrated in the original example above (we had 10 numbers in the
-input and 10 points in the plot). If requested, the script supports more
-sophisticated interpretation of input data
-
-=head3 Domain selection
-
-If C<--domain> is passed in, the first value on each line of input is
-interpreted as the I<X>-value for the rest of the data on that line. Without
-C<--domain> the I<X>-value is the line number, and the first value on a line is
-a plain data point like the others. Default is C<--nodomain>. Thus the original
-example above produces 2 curves, with B<1,2,3,4,5> as the I<X>-values. If we run
-the same command with --domain:
-
- $ seq 5 | awk '{print 2*$1, $1*$1}' | feedgnuplot --domain
-
-we get only 1 curve, with B<2,4,6,8,10> as the I<X>-values. As many points as
-desired can appear on a single line, but all points on a line are associated
-with the I<X>-value at the start of that line.
-
-=head3 Curve indexing
-
-By default, each column represents a separate curve. This is fine unless sparse
-data is to be plotted. With the C<--dataid> option, each point is represented by
-2 values: a string identifying the curve, and the value itself. If we add
-C<--dataid> to the original example:
-
- $ seq 5 | awk '{print 2*$1, $1*$1}' | feedgnuplot --dataid --autolegend
-
-we get 5 different curves with one point in each. The first column, as produced
-by C<awk>, is B<2,4,6,8,10>. These are interpreted as the IDs of the curves to
-be plotted. The C<--autolegend> option adds a legend using the given IDs to
-label the curves. The IDs need not be numbers; generic strings are accepted. As
-many points as desired can appear on a single line. C<--domain> can be used in
-conjunction with C<--dataid>.
-
-=head3 Multi-value style support
-
-Depending on how gnuplot is plotting the data, more than one value may be needed
-to represent a single point. For example, the script has support to plot all the
-data with C<--circles>. This requires a radius to be specified for each point in
-addition to the position of the point. Thus, when plotting with C<--circles>, 2
-numbers are read for each data point instead of 1. A similar situation exists
-with C<--colormap> where each point contains the position I<and> the
-color. There are other gnuplot styles that require more data (such as error
-bars), but none of these are directly supported by the script. They can still be
-used, though, by specifying the specific style with C<--curvestyle>, and
-specifying how many extra values are needed for each point with
-C<--extraValuesPerPoint extra>. C<--extraValuesPerPoint> is ONLY needed for the
-styles not explicitly supported; supported styles set that variable
-automatically.
-
-=head3 3D data
-
-To plot 3D data, pass in C<--3d>. C<--domain> MUST be given when plotting 3D
-data to avoid domain ambiguity. If 3D data is being plotted, there are by
-definition 2 domain values instead of one (I<Z> as a function of I<X> and I<Y>
-instead of I<Y> as a function of I<X>). Thus the first 2 values on each line are
-interpreted as the domain instead of just 1. The rest of the processing happens
-the same way as before.
-
-=head3 Special data commands
-
-Other than the raw data, 2 special commands are interpreted if they appear in
-the input. These are C<replot> and C<clear>. If a line of data begins with
-C<replot> and we're plotting in realtime with C<--stream>, the plot will be
-refreshed immediately. If a line of data begins with C<clear>, the plot is
-cleared, to be re-filled with any data following the C<clear>.
-
-=head2 Real-time streaming data
-
-To plot real-time data, pass in the C<--stream [refreshperiod]> option. Data
-will then be plotted as it is received. The plot will be updated every
-C<refreshperiod> seconds. If the period isn't specified, a 1Hz refresh rate is
-used. To refresh at specific intervals indicated by the data, set the
-refreshperiod to 0 or to 'trigger'. The plot will then I<only> be refreshed when
-a data line 'replot' is received. This 'replot' command works in both triggered
-and timed modes, but in triggered mode, it's the only way to replot.
-
-To plot only the most recent data (instead of I<all> the data), C<--xlen
-windowsize> can be given. This will create an constantly-updating, scrolling
-view of the recent past. C<windowsize> should be replaced by the desired length
-of the domain window to plot, in domain units (passed-in values if C<--domain>
-or line numbers otherwise).
-
-=head2 Hardcopy output
-
-The script is able to produce hardcopy output with C<--hardcopy outputfile>. The
-output type is inferred from the filename with B<.ps>, B<.eps>, B<.pdf> and
-B<.png> currently supported.
-
-=head2 Self-plotting data files
-
-This script can be used to enable self-plotting data files. There are 2 ways of
-doing this: with a shebang (#!) or with inline perl data.
-
-=head3 Self-plotting data with a #!
-
-A self-plotting, executable data file C<data> is formatted as
-
- $ cat data
- #!/usr/bin/feedgnuplot --lines --points
- 2 1
- 4 4
- 6 9
- 8 16
- 10 25
- 12 36
- 14 49
- 16 64
- 18 81
- 20 100
- 22 121
- 24 144
- 26 169
- 28 196
- 30 225
-
-This is the shebang (#!) line followed by the data, formatted as before. The
-data file can be plotted simply with
-
- $ ./data
-
-The caveats here are that on Linux the whole #! line is limited to 127 charaters
-and that the full path to feedgnuplot must be given. The 127 character limit is
-a serious limitation, but this can likely be resolved with a kernel patch. I
-have only tried on Linux 2.6.
-
-=head3 Self-plotting data with perl inline data
-
-Perl supports storing data and code in the same file. This can also be used to
-create self-plotting files:
-
- $ cat plotdata.pl
- #!/usr/bin/perl
- use strict;
- use warnings;
-
- open PLOT, "| feedgnuplot --lines --points" or die "Couldn't open plotting pipe";
- while( <DATA> )
- {
-   my @xy = split;
-   print PLOT "@xy\n";
- }
- __DATA__
- 2 1
- 4 4
- 6 9
- 8 16
- 10 25
- 12 36
- 14 49
- 16 64
- 18 81
- 20 100
- 22 121
- 24 144
- 26 169
- 28 196
- 30 225
-
-This is especially useful if the logged data is not in a format directly
-supported by feedgnuplot. Raw data can be stored after the __DATA__ directive,
-with a small perl script to manipulate the data into a useable format and send
-it to the plotter.
-
-=head1 ARGUMENTS
-
-  --[no]domain         If enabled, the first element of each line is the
-                       domain variable.  If not, the point index is used
-
-  --[no]dataid         If enabled, each data point is preceded by the ID
-                       of the data set that point corresponds to. This ID is
-                       interpreted as a string, NOT as just a number. If not
-                       enabled, the order of the point is used.
-
-As an example, if line 3 of the input is "0 9 1 20"
- '--nodomain --nodataid' would parse the 4 numbers as points in 4
-   different curves at x=3
-
- '--domain --nodataid' would parse the 4 numbers as points in 3 different
-   curves at x=0. Here, 0 is the x-variable and 9,1,20 are the data values
-
- '--nodomain --dataid' would parse the 4 numbers as points in 2 different
-   curves at x=3. Here 0 and 1 are the data IDs and 9 and 20 are the
-   data values
-
- '--domain --dataid' would parse the 4 numbers as a single point at
-   x=0. Here 9 is the data ID and 1 is the data value. 20 is an extra
-   value, so it is ignored. If another value followed 20, we'd get another
-   point in curve ID 20
-
-  --[no]3d             Do [not] plot in 3D. This only makes sense with --domain.
-                       Each domain here is an (x,y) tuple
-
-  --colormap           Show a colormapped xy plot. Requires extra data for the color.
-                       zmin/zmax can be used to set the extents of the colors.
-                       Automatically increments extraValuesPerPoint
-
-  --stream [period]    Plot the data as it comes in, in realtime. If period is given,
-                       replot every period seconds. If no period is given, replot at
-                       1Hz. If the period is given as 0 or 'trigger', replot ONLY when
-                       the incoming data dictates this . See the "Real-time streaming
-                       data" section of the man page.
-
-  --[no]lines          Do [not] draw lines to connect consecutive points
-  --[no]points         Do [not] draw points
-  --circles            Plot with circles. This requires a radius be specified for
-                       each point. Automatically increments extraValuesPerPoint
-
-  --xlabel xxx         Set x-axis label
-  --ylabel xxx         Set y-axis label
-  --y2label xxx        Set y2-axis label. Does not apply to 3d plots
-  --zlabel xxx         Set y-axis label. Only applies to 3d plots
-
-  --title  xxx         Set the title of the plot
-
-  --legend curveID legend
-                       Set the label for a curve plot. Use this option multiple times
-                       for multiple curves. With --dataid, curveID is the ID. Otherwise,
-                       it's the index of the curve, starting at 0
-
-  --autolegend         Use the curve IDs for the legend. Titles given with --legend
-                       override these
-
-  --xlen xxx           When using --stream, sets the size of the x-window to plot.
-                       Omit this or set it to 0 to plot ALL the data. Does not
-                       make sense with 3d plots. Implies --monotonic
-
-  --xmin  xxx          Set the range for the x axis. These are ignored in a
-                       streaming plot
-  --xmax  xxx          Set the range for the x axis. These are ignored in a
-                       streaming plot
-  --ymin  xxx          Set the range for the y axis.
-  --ymax  xxx          Set the range for the y axis.
-  --y2min xxx          Set the range for the y2 axis. Does not apply to 3d plots.
-  --y2max xxx          Set the range for the y2 axis. Does not apply to 3d plots.
-  --zmin  xxx          Set the range for the z axis. Only applies to 3d plots or colormaps.
-  --zmax  xxx          Set the range for the z axis. Only applies to 3d plots or colormaps.
-
-  --y2    xxx          Plot the data specified by this curve ID on the y2 axis.
-                       Without --dataid, the ID is just an ordered 0-based index.
-                       Does not apply to 3d plots.
-
-  --curvestyle curveID style
-                       Additional styles per curve. With --dataid, curveID is the
-                       ID. Otherwise, it's the index of the curve, starting at 0. Use
-                       this option multiple times for multiple curves
-
-  --curvestyleall xxx  Additional styles for ALL curves.
-
-  --extracmds xxx      Additional commands. These could contain extra global styles
-                       for instance
-
-  --size  xxx          Gnuplot size option
-
-  --square             Plot data with aspect ratio 1. For 3D plots, this controls the
-                       aspect ratio for all 3 axes
-
-  --square_xy          For 3D plots, set square aspect ratio for ONLY the x,y axes
-
-  --hardcopy xxx       If not streaming, output to a file specified here. Format
-                       inferred from filename
-
-  --maxcurves xxx      The maximum allowed number of curves. This is 100 by default,
-                       but can be reset with this option. This exists purely to
-                       prevent perl from allocating all of the system's memory when
-                       reading bogus data
-
-  --monotonic          If --domain is given, checks to make sure that the x-
-                       coordinate in the input data is monotonically increasing.
-                       If a given x-variable is in the past, all data currently
-                       cached for this curve is purged. Without --monotonic, all
-                       data is kept. Does not make sense with 3d plots.
-                       No --monotonic by default.
-
-  --extraValuesPerPoint xxx
-                       How many extra values are given for each data point. Normally this

-

-=head1 NAME
-
-feedgnuplot - Pipe-oriented frontend to Gnuplot
-
-=head1 SYNOPSIS
-
-Simple plotting of stored data:
-
- $ seq 5 | awk '{print 2*$1, $1*$1}'
- 2 1
- 4 4
- 6 9
- 8 16
- 10 25
-
- $ seq 5 | awk '{print 2*$1, $1*$1}' |
-   feedgnuplot --lines --points --legend 0 "data 0" --title "Test plot" --y2 1
-
-Simple real-time plotting example: plot how much data is received on the wlan0
-network interface in bytes/second (uses bash, awk and Linux):
-
- $ while true; do sleep 1; cat /proc/net/dev; done |
-   gawk '/wlan0/ {if(b) {print $2-b; fflush()} b=$2}' |
-   feedgnuplot --lines --stream --xlen 10 --ylabel 'Bytes/sec' --xlabel seconds
-
-=head1 DESCRIPTION
-
-This is a flexible, command-line-oriented frontend to Gnuplot. It creates
-plots from data coming in on STDIN or given in a filename passed on the
-commandline. Various data representations are supported, as is hardcopy
-output and streaming display of live data. A simple example:
-
- $ seq 5 | awk '{print 2*$1, $1*$1}' | feedgnuplot
-
-You should see a plot with two curves. The C<awk> command generates some data to
-plot and the C<feedgnuplot> reads it in from STDIN and generates the plot. The
-C<awk> invocation is just an example; more interesting things would be plotted
-in normal usage. No commandline-options are required for the most basic
-plotting. Input parsing is flexible; every line need not have the same number of
-points. New curves will be created as needed.
-
-The most commonly used functionality of gnuplot is supported directly by the
-script. Anything not directly supported can still be done with the
-C<--extracmds> and C<--curvestyle> options. Arbitrary gnuplot commands can be
-passed in with C<--extracmds>. For example, to turn off the grid, pass in
-C<--extracmds 'unset grid'>. As many of these options as needed can be passed
-in. To add arbitrary curve styles, use C<--curvestyle curveID extrastyle>. Pass
-these more than once to affect more than one curve. To apply an extra style to
-I<all> the curves, pass in C<--curvestyleall extrastyle>.
-
-=head2 Data formats
-
-By default, each value present in the incoming data represents a distinct data
-point, as demonstrated in the original example above (we had 10 numbers in the
-input and 10 points in the plot). If requested, the script supports more
-sophisticated interpretation of input data
-
-=head3 Domain selection
-
-If C<--domain> is passed in, the first value on each line of input is
-interpreted as the I<X>-value for the rest of the data on that line. Without
-C<--domain> the I<X>-value is the line number, and the first value on a line is
-a plain data point like the others. Default is C<--nodomain>. Thus the original
-example above produces 2 curves, with B<1,2,3,4,5> as the I<X>-values. If we run
-the same command with --domain:
-
- $ seq 5 | awk '{print 2*$1, $1*$1}' | feedgnuplot --domain
-
-we get only 1 curve, with B<2,4,6,8,10> as the I<X>-values. As many points as
-desired can appear on a single line, but all points on a line are associated
-with the I<X>-value at the start of that line.
-
-=head3 Curve indexing
-
-By default, each column represents a separate curve. This is fine unless sparse
-data is to be plotted. With the C<--dataid> option, each point is represented by
-2 values: a string identifying the curve, and the value itself. If we add
-C<--dataid> to the original example:
-
- $ seq 5 | awk '{print 2*$1, $1*$1}' | feedgnuplot --dataid --autolegend
-
-we get 5 different curves with one point in each. The first column, as produced
-by C<awk>, is B<2,4,6,8,10>. These are interpreted as the IDs of the curves to
-be plotted. The C<--autolegend> option adds a legend using the given IDs to
-label the curves. The IDs need not be numbers; generic strings are accepted. As
-many points as desired can appear on a single line. C<--domain> can be used in
-conjunction with C<--dataid>.
-
-=head3 Multi-value style support
-
-Depending on how gnuplot is plotting the data, more than one value may be needed
-to represent a single point. For example, the script has support to plot all the
-data with C<--circles>. This requires a radius to be specified for each point in
-addition to the position of the point. Thus, when plotting with C<--circles>, 2
-numbers are read for each data point instead of 1. A similar situation exists
-with C<--colormap> where each point contains the position I<and> the
-color. There are other gnuplot styles that require more data (such as error
-bars), but none of these are directly supported by the script. They can still be
-used, though, by specifying the specific style with C<--curvestyle>, and
-specifying how many extra values are needed for each point with
-C<--extraValuesPerPoint extra>. C<--extraValuesPerPoint> is ONLY needed for the
-styles not explicitly supported; supported styles set that variable
-automatically.
-
-=head3 3D data
-
-To plot 3D data, pass in C<--3d>. C<--domain> MUST be given when plotting 3D
-data to avoid domain ambiguity. If 3D data is being plotted, there are by
-definition 2 domain values instead of one (I<Z> as a function of I<X> and I<Y>
-instead of I<Y> as a function of I<X>). Thus the first 2 values on each line are
-interpreted as the domain instead of just 1. The rest of the processing happens
-the same way as before.
-
-=head3 Special data commands
-
-Other than the raw data, 2 special commands are interpreted if they appear in
-the input. These are C<replot> and C<clear>. If a line of data begins with
-C<replot> and we're plotting in realtime with C<--stream>, the plot will be
-refreshed immediately. If a line of data begins with C<clear>, the plot is
-cleared, to be re-filled with any data following the C<clear>.
-
-=head2 Real-time streaming data
-
-To plot real-time data, pass in the C<--stream [refreshperiod]> option. Data
-will then be plotted as it is received. The plot will be updated every
-C<refreshperiod> seconds. If the period isn't specified, a 1Hz refresh rate is
-used. To refresh at specific intervals indicated by the data, set the
-refreshperiod to 0 or to 'trigger'. The plot will then I<only> be refreshed when
-a data line 'replot' is received. This 'replot' command works in both triggered
-and timed modes, but in triggered mode, it's the only way to replot.
-
-To plot only the most recent data (instead of I<all> the data), C<--xlen
-windowsize> can be given. This will create an constantly-updating, scrolling
-view of the recent past. C<windowsize> should be replaced by the desired length
-of the domain window to plot, in domain units (passed-in values if C<--domain>
-or line numbers otherwise).
-
-=head2 Hardcopy output
-
-The script is able to produce hardcopy output with C<--hardcopy outputfile>. The
-output type is inferred from the filename with B<.ps>, B<.eps>, B<.pdf> and
-B<.png> currently supported.
-
-=head2 Self-plotting data files
-
-This script can be used to enable self-plotting data files. There are 2 ways of
-doing this: with a shebang (#!) or with inline perl data.
-
-=head3 Self-plotting data with a #!
-
-A self-plotting, executable data file C<data> is formatted as
-
- $ cat data
- #!/usr/bin/feedgnuplot --lines --points
- 2 1
- 4 4
- 6 9
- 8 16
- 10 25
- 12 36
- 14 49
- 16 64
- 18 81
- 20 100
- 22 121
- 24 144
- 26 169
- 28 196
- 30 225
-
-This is the shebang (#!) line followed by the data, formatted as before. The
-data file can be plotted simply with
-
- $ ./data
-
-The caveats here are that on Linux the whole #! line is limited to 127 charaters
-and that the full path to feedgnuplot must be given. The 127 character limit is
-a serious limitation, but this can likely be resolved with a kernel patch. I
-have only tried on Linux 2.6.
-
-=head3 Self-plotting data with perl inline data
-
-Perl supports storing data and code in the same file. This can also be used to
-create self-plotting files:
-
- $ cat plotdata.pl
- #!/usr/bin/perl
- use strict;
- use warnings;
-
- open PLOT, "| feedgnuplot --lines --points" or die "Couldn't open plotting pipe";
- while( <DATA> )
- {
-   my @xy = split;
-   print PLOT "@xy\n";
- }
- __DATA__
- 2 1
- 4 4
- 6 9
- 8 16
- 10 25
- 12 36
- 14 49
- 16 64
- 18 81
- 20 100
- 22 121
- 24 144
- 26 169
- 28 196
- 30 225
-
-This is especially useful if the logged data is not in a format directly
-supported by feedgnuplot. Raw data can be stored after the __DATA__ directive,
-with a small perl script to manipulate the data into a useable format and send
-it to the plotter.
-
-=head1 ARGUMENTS
-
-  --[no]domain         If enabled, the first element of each line is the
-                       domain variable.  If not, the point index is used
-
-  --[no]dataid         If enabled, each data point is preceded by the ID
-                       of the data set that point corresponds to. This ID is
-                       interpreted as a string, NOT as just a number. If not
-                       enabled, the order of the point is used.
-
-As an example, if line 3 of the input is "0 9 1 20"
- '--nodomain --nodataid' would parse the 4 numbers as points in 4
-   different curves at x=3
-
- '--domain --nodataid' would parse the 4 numbers as points in 3 different
-   curves at x=0. Here, 0 is the x-variable and 9,1,20 are the data values
-
- '--nodomain --dataid' would parse the 4 numbers as points in 2 different
-   curves at x=3. Here 0 and 1 are the data IDs and 9 and 20 are the
-   data values
-
- '--domain --dataid' would parse the 4 numbers as a single point at
-   x=0. Here 9 is the data ID and 1 is the data value. 20 is an extra
-   value, so it is ignored. If another value followed 20, we'd get another
-   point in curve ID 20
-
-  --[no]3d             Do [not] plot in 3D. This only makes sense with --domain.
-                       Each domain here is an (x,y) tuple
-
-  --colormap           Show a colormapped xy plot. Requires extra data for the color.
-                       zmin/zmax can be used to set the extents of the colors.
-                       Automatically increments extraValuesPerPoint
-
-  --stream [period]    Plot the data as it comes in, in realtime. If period is given,
-                       replot every period seconds. If no period is given, replot at
-                       1Hz. If the period is given as 0 or 'trigger', replot ONLY when
-                       the incoming data dictates this . See the "Real-time streaming
-                       data" section of the man page.
-
-  --[no]lines          Do [not] draw lines to connect consecutive points
-  --[no]points         Do [not] draw points
-  --circles            Plot with circles. This requires a radius be specified for
-                       each point. Automatically increments extraValuesPerPoint
-
-  --xlabel xxx         Set x-axis label
-  --ylabel xxx         Set y-axis label
-  --y2label xxx        Set y2-axis label. Does not apply to 3d plots
-  --zlabel xxx         Set y-axis label. Only applies to 3d plots
-
-  --title  xxx         Set the title of the plot
-
-  --legend curveID legend
-                       Set the label for a curve plot. Use this option multiple times
-                       for multiple curves. With --dataid, curveID is the ID. Otherwise,

+=head1 NAME
+
+feedgnuplot - Pipe-oriented frontend to Gnuplot
+
+=head1 SYNOPSIS
+
+Simple plotting of stored data:
+
+ $ seq 5 | awk '{print 2*$1, $1*$1}'
+ 2 1
+ 4 4
+ 6 9
+ 8 16
+ 10 25
+
+ $ seq 5 | awk '{print 2*$1, $1*$1}' |
+   feedgnuplot --lines --points --legend 0 "data 0" --title "Test plot" --y2 1
+
+Simple real-time plotting example: plot how much data is received on the wlan0
+network interface in bytes/second (uses bash, awk and Linux):
+
+ $ while true; do sleep 1; cat /proc/net/dev; done |
+   gawk '/wlan0/ {if(b) {print $2-b; fflush()} b=$2}' |
+   feedgnuplot --lines --stream --xlen 10 --ylabel 'Bytes/sec' --xlabel seconds
+
+=head1 DESCRIPTION
+
+This is a flexible, command-line-oriented frontend to Gnuplot. It creates
+plots from data coming in on STDIN or given in a filename passed on the
+commandline. Various data representations are supported, as is hardcopy
+output and streaming display of live data. A simple example:
+
+ $ seq 5 | awk '{print 2*$1, $1*$1}' | feedgnuplot
+
+You should see a plot with two curves. The C<awk> command generates some data to
+plot and the C<feedgnuplot> reads it in from STDIN and generates the plot. The
+C<awk> invocation is just an example; more interesting things would be plotted
+in normal usage. No commandline-options are required for the most basic
+plotting. Input parsing is flexible; every line need not have the same number of
+points. New curves will be created as needed.
+
+The most commonly used functionality of gnuplot is supported directly by the
+script. Anything not directly supported can still be done with the
+C<--extracmds> and C<--curvestyle> options. Arbitrary gnuplot commands can be
+passed in with C<--extracmds>. For example, to turn off the grid, pass in
+C<--extracmds 'unset grid'>. As many of these options as needed can be passed
+in. To add arbitrary curve styles, use C<--curvestyle curveID extrastyle>. Pass
+these more than once to affect more than one curve. To apply an extra style to
+I<all> the curves that lack an explicit C<--curvestyle>, pass in
+C<--curvestyleall extrastyle>.
+
+=head2 Data formats
+
+By default, each value present in the incoming data represents a distinct data
+point, as demonstrated in the original example above (we had 10 numbers in the
+input and 10 points in the plot). If requested, the script supports more
+sophisticated interpretation of input data
+
+=head3 Domain selection
+
+If C<--domain> is passed in, the first value on each line of input is
+interpreted as the I<X>-value for the rest of the data on that line. Without
+C<--domain> the I<X>-value is the line number, and the first value on a line is
+a plain data point like the others. Default is C<--nodomain>. Thus the original
+example above produces 2 curves, with B<1,2,3,4,5> as the I<X>-values. If we run
+the same command with --domain:
+
+ $ seq 5 | awk '{print 2*$1, $1*$1}' | feedgnuplot --domain
+
+we get only 1 curve, with B<2,4,6,8,10> as the I<X>-values. As many points as
+desired can appear on a single line, but all points on a line are associated
+with the I<X>-value at the start of that line.
+
+=head3 Curve indexing
+
+By default, each column represents a separate curve. This is fine unless sparse
+data is to be plotted. With the C<--dataid> option, each point is represented by
+2 values: a string identifying the curve, and the value itself. If we add
+C<--dataid> to the original example:
+
+ $ seq 5 | awk '{print 2*$1, $1*$1}' | feedgnuplot --dataid --autolegend
+
+we get 5 different curves with one point in each. The first column, as produced
+by C<awk>, is B<2,4,6,8,10>. These are interpreted as the IDs of the curves to
+be plotted. The C<--autolegend> option adds a legend using the given IDs to
+label the curves. The IDs need not be numbers; generic strings are accepted. As
+many points as desired can appear on a single line. C<--domain> can be used in
+conjunction with C<--dataid>.
+
+=head3 Multi-value style support
+
+Depending on how gnuplot is plotting the data, more than one value may be needed
+to represent a single point. For example, the script has support to plot all the
+data with C<--circles>. This requires a radius to be specified for each point in
+addition to the position of the point. Thus, when plotting with C<--circles>, 2
+numbers are read for each data point instead of 1. A similar situation exists
+with C<--colormap> where each point contains the position I<and> the
+color. There are other gnuplot styles that require more data (such as error
+bars), but none of these are directly supported by the script. They can still be
+used, though, by specifying the specific style with C<--curvestyle>, and
+specifying how many extra values are needed for each point with
+C<--extraValuesPerPoint extra>. C<--extraValuesPerPoint> is ONLY needed for the
+styles not explicitly supported; supported styles set that variable
+automatically.
+
+=head3 3D data
+
+To plot 3D data, pass in C<--3d>. C<--domain> MUST be given when plotting 3D
+data to avoid domain ambiguity. If 3D data is being plotted, there are by
+definition 2 domain values instead of one (I<Z> as a function of I<X> and I<Y>
+instead of I<Y> as a function of I<X>). Thus the first 2 values on each line are
+interpreted as the domain instead of just 1. The rest of the processing happens
+the same way as before.
+
+=head3 Special data commands
+
+Other than the raw data, 2 special commands are interpreted if they appear in
+the input. These are C<replot> and C<clear>. If a line of data begins with
+C<replot> and we're plotting in realtime with C<--stream>, the plot will be
+refreshed immediately. If a line of data begins with C<clear>, the plot is
+cleared, to be re-filled with any data following the C<clear>.
+
+=head2 Real-time streaming data
+
+To plot real-time data, pass in the C<--stream [refreshperiod]> option. Data
+will then be plotted as it is received. The plot will be updated every
+C<refreshperiod> seconds. If the period isn't specified, a 1Hz refresh rate is
+used. To refresh at specific intervals indicated by the data, set the
+refreshperiod to 0 or to 'trigger'. The plot will then I<only> be refreshed when
+a data line 'replot' is received. This 'replot' command works in both triggered
+and timed modes, but in triggered mode, it's the only way to replot.
+
+To plot only the most recent data (instead of I<all> the data), C<--xlen
+windowsize> can be given. This will create an constantly-updating, scrolling
+view of the recent past. C<windowsize> should be replaced by the desired length
+of the domain window to plot, in domain units (passed-in values if C<--domain>
+or line numbers otherwise).
+
+=head2 Hardcopy output
+
+The script is able to produce hardcopy output with C<--hardcopy outputfile>. The
+output type can be inferred from the filename, if B<.ps>, B<.eps>, B<.pdf>,
+B<.svg> or B<.png> is requested. If any other file type is requested,
+C<--terminal> I<must> be passed in to tell gnuplot how to make the plot.
+
+=head2 Self-plotting data files
+
+This script can be used to enable self-plotting data files. There are 2 ways of
+doing this: with a shebang (#!) or with inline perl data.
+
+=head3 Self-plotting data with a #!
+
+A self-plotting, executable data file C<data> is formatted as
+
+ $ cat data
+ #!/usr/bin/feedgnuplot --lines --points
+ 2 1
+ 4 4
+ 6 9
+ 8 16
+ 10 25
+ 12 36
+ 14 49
+ 16 64
+ 18 81
+ 20 100
+ 22 121
+ 24 144
+ 26 169
+ 28 196
+ 30 225
+
+This is the shebang (#!) line followed by the data, formatted as before. The
+data file can be plotted simply with
+
+ $ ./data
+
+The caveats here are that on Linux the whole #! line is limited to 127 charaters
+and that the full path to feedgnuplot must be given. The 127 character limit is
+a serious limitation, but this can likely be resolved with a kernel patch. I
+have only tried on Linux 2.6.
+
+=head3 Self-plotting data with perl inline data
+
+Perl supports storing data and code in the same file. This can also be used to
+create self-plotting files:
+
+ $ cat plotdata.pl
+ #!/usr/bin/perl
+ use strict;
+ use warnings;
+
+ open PLOT, "| feedgnuplot --lines --points" or die "Couldn't open plotting pipe";
+ while( <DATA> )
+ {
+   my @xy = split;
+   print PLOT "@xy\n";
+ }
+ __DATA__
+ 2 1
+ 4 4
+ 6 9
+ 8 16
+ 10 25
+ 12 36
+ 14 49
+ 16 64
+ 18 81
+ 20 100
+ 22 121
+ 24 144
+ 26 169
+ 28 196
+ 30 225
+
+This is especially useful if the logged data is not in a format directly
+supported by feedgnuplot. Raw data can be stored after the __DATA__ directive,
+with a small perl script to manipulate the data into a useable format and send
+it to the plotter.
+
+=head1 ARGUMENTS
+
+  --[no]domain         If enabled, the first element of each line is the
+                       domain variable.  If not, the point index is used
+
+  --[no]dataid         If enabled, each data point is preceded by the ID
+                       of the data set that point corresponds to. This ID is
+                       interpreted as a string, NOT as just a number. If not
+                       enabled, the order of the point is used.
+
+As an example, if line 3 of the input is "0 9 1 20"
+ '--nodomain --nodataid' would parse the 4 numbers as points in 4
+   different curves at x=3
+
+ '--domain --nodataid' would parse the 4 numbers as points in 3 different
+   curves at x=0. Here, 0 is the x-variable and 9,1,20 are the data values
+
+ '--nodomain --dataid' would parse the 4 numbers as points in 2 different
+   curves at x=3. Here 0 and 1 are the data IDs and 9 and 20 are the
+   data values
+
+ '--domain --dataid' would parse the 4 numbers as a single point at
+   x=0. Here 9 is the data ID and 1 is the data value. 20 is an extra
+   value, so it is ignored. If another value followed 20, we'd get another
+   point in curve ID 20
+
+  --[no]3d             Do [not] plot in 3D. This only makes sense with --domain.
+                       Each domain here is an (x,y) tuple
+
+  --colormap           Show a colormapped xy plot. Requires extra data for the color.
+                       zmin/zmax can be used to set the extents of the colors.
+                       Automatically increments extraValuesPerPoint
+
+  --stream [period]    Plot the data as it comes in, in realtime. If period is given,
+                       replot every period seconds. If no period is given, replot at
+                       1Hz. If the period is given as 0 or 'trigger', replot ONLY when
+                       the incoming data dictates this . See the "Real-time streaming
+                       data" section of the man page.
+
+  --[no]lines          Do [not] draw lines to connect consecutive points
+  --[no]points         Do [not] draw points
+  --circles            Plot with circles. This requires a radius be specified for
+                       each point. Automatically increments extraValuesPerPoint
+
+  --xlabel xxx         Set x-axis label
+  --ylabel xxx         Set y-axis label
+  --y2label xxx        Set y2-axis label. Does not apply to 3d plots
+  --zlabel xxx         Set y-axis label. Only applies to 3d plots
+
+  --title  xxx         Set the title of the plot
+
+  --legend curveID legend
+                       Set the label for a curve plot. Use this option multiple times
+                       for multiple curves. With --dataid, curveID is the ID. Otherwise,
+                       it's the index of the curve, starting at 0
+
+  --autolegend         Use the curve IDs for the legend. Titles given with --legend
+                       override these
+
+  --xlen xxx           When using --stream, sets the size of the x-window to plot.
+                       Omit this or set it to 0 to plot ALL the data. Does not
+                       make sense with 3d plots. Implies --monotonic
+
+  --xmin  xxx          Set the range for the x axis. These are ignored in a
+                       streaming plot
+  --xmax  xxx          Set the range for the x axis. These are ignored in a
+                       streaming plot
+  --ymin  xxx          Set the range for the y axis.
+  --ymax  xxx          Set the range for the y axis.
+  --y2min xxx          Set the range for the y2 axis. Does not apply to 3d plots.
+  --y2max xxx          Set the range for the y2 axis. Does not apply to 3d plots.
+  --zmin  xxx          Set the range for the z axis. Only applies to 3d plots or colormaps.
+  --zmax  xxx          Set the range for the z axis. Only applies to 3d plots or colormaps.
+
+  --y2    xxx          Plot the data specified by this curve ID on the y2 axis.
+                       Without --dataid, the ID is just an ordered 0-based index.
+                       Does not apply to 3d plots. Can be passed multiple times, or passed a
+                       comma-separated list
+
+  --histogram  curveID
+                       Set up a this specific curve to plot a histogram. The bin
+                       width is given with the --binwidth option (assumed 1.0 if
+                       omitted). --histogram does NOT touch the drawing style.
+                       It is often desired to plot these with boxes, and this
+                       MUST be explicitly requested with --curvestyleall 'with
+                       boxes'. This works with --domain and/or --stream, but in
+                       those cases the x-value is used ONLY to cull old data
+                       because of --xlen or --monotonic. I.e. the x-values are
+                       NOT drawn in any way. Can be passed multiple times, or passed a comma-
+                       separated list
+  --binwidth width     The width of bins when making histograms. This setting applies to ALL
+                       histograms in the plot. Defaults to 1.0 if not given.
+  --histstyle style    Normally, histograms are generated with the 'smooth freq'
+                       gnuplot style. --histstyle can be used to select
+                       different 'smooth' settings. Allowed are 'unique',
+                       'cumulative' and 'cnormal'. 'unique' indicates whether a
+                       bin has at least one item in it: instead of counting the
+                       items, it'll always report 0 or 1. 'cumulative' is the
+                       integral of the "normal" histogram. 'cnormal' is like
+                       'cumulative', but rescaled to end up at 1.0.
+
+  --curvestyle curveID style
+                       Additional styles per curve. With --dataid, curveID is
+                       the ID. Otherwise, it's the index of the curve, starting
+                       at 0. Use this option multiple times for multiple curves.
+                       --curvestylall does NOT apply to curves that have a
+                       --curvestyle
+
+  --curvestyleall xxx  Additional styles for all curves that have no --curvestyle
+
+  --extracmds xxx      Additional commands. These could contain extra global styles
+                       for instance. Can be passed multiple times.
+
+  --square             Plot data with aspect ratio 1. For 3D plots, this controls the
+                       aspect ratio for all 3 axes
+
+  --square_xy          For 3D plots, set square aspect ratio for ONLY the x,y axes
+
+  --hardcopy xxx       If not streaming, output to a file specified here. Format
+                       inferred from filename, unless specified by --terminal
+  --terminal xxx       String passed to 'set terminal'. No attempts are made to
+                       validate this. --hardcopy sets this to some sensible
+                       defaults if --hardcopy is given .png, .pdf, .ps, .eps or
+                       .svg. If any other file type is desired, use both
+                       --hardcopy and --terminal
+
+  --maxcurves xxx      The maximum allowed number of curves. This is 100 by default,
+                       but can be reset with this option. This exists purely to
+                       prevent perl from allocating all of the system's memory when
+                       reading bogus data
+
+  --monotonic          If --domain is given, checks to make sure that the x-
+                       coordinate in the input data is monotonically increasing.
+                       If a given x-variable is in the past, all data currently
+                       cached for this curve is purged. Without --monotonic, all
+                       data is kept. Does not make sense with 3d plots.
+                       No --monotonic by default.
+
+  --extraValuesPerPoint xxx
+                       How many extra values are given for each data point. Normally this
+                       is 0, and does not need to be specified, but sometimes we want
+                       extra data, like for colors or point sizes or error bars, etc.
+                       feedgnuplot options that require this (colormap, circles)
+                       automatically set it. This option is ONLY needed if unknown styles are
+                       used, with --curvestyleall for instance
+
+  --dump               Instead of printing to gnuplot, print to STDOUT. For
+                       debugging.
+
+  --geometry           If using X11, specifies the size, position of the plot window
