Usage: $0 [options] file1 file2 ...
|
||||
any number of data files can be given on the cmdline. They will be processed
|
||||
in sequence. If no data files are given, data will be read in from standard
|
||||
input.
|
||||
|
||||
--[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
|
||||
|
||||
--[no]stream Do [not] display the data a point at a time, as it
|
||||
comes in
|
||||
|
||||
--[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
|
||||
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)

used, with --curvestyleall for instance
