+=head3 'using' expressions
+
+We just described how feedgnuplot parses its input data. When passing this data
+to gnuplot, each curve is sent independently. The domain appears in the leading
+columns followed by C<--rangesize> columns to complete each row. Without
+C<--domain>, feedgnuplot explicitly writes out sequential integers. gnuplot then
+knows how many values it has for each point, and it knows which style we're
+using, so it's able to interpret the data appropriately, and to make the correct
+plot.
+
+As an example, if gnuplot is passed 2 columns of data, and it is plotting C<with
+points>, it will use column 1 for the x coordinate and column 2 for the y
+coordinate. This is the default behavior, but the meaning of each column can be
+controlled via a C<using> expression in gnuplot (not feedgnuplot; keep reading).
+The default is sequential integers, so this example uses C<using 1:2> by
+default. We can flip the meaning of the columns by passing C<using 2:1>.
+Arbitrary expressions may be specified by enclosing each field in C<()>, and
+using C<$> to denote each data column. So to use the 2nd column as the x
+coordinate and the sum of the two columns as the y coordinate, C<using
+2:($1+$2)> is passed. Furthermore, the number of columns can vary. For instance
+gnuplot can read the same two columns of data, but produce a plot with the extra
+column encoding the sum as the color: C<using 1:2:($1+$2) with points palette>.
+Please see the gnuplot documentation for lots of detail.
+
+That's how I<gnuplot> works. Most of the time, I<feedgnuplot> doesn't pass any
+C<using> expressions at all, and gnuplot does the default thing. But if we want
+to do something fancy, feedgnuplot supports C<--using curveID expression> and
+C<--usingall expression>. So we can plot a parabola:
+
+  seq 100 | feedgnuplot --lines --usingall '1:($2*$2)'
+
+This is powerful, but there are some things to keep in mind:
+
+=over
+
+=item
+
+C<--using> overrides whatever C<using> expression feedgnuplot was going to pass.
+feedgnuplot passes a C<using> expression only if C<--histogram> or C<--timefmt>
+or C<--xticlabels> are given. So if C<--using> is given together with any of
+these, the user must take care to do the right thing (whatever that means at
+that time).
+
+=item
+
+The C<--tuplesize> controls the data passed to feedgnuplot and the data then
+passed to gnuplot. It does I<not> directly control how gnuplot eventually
+interprets the data: C<--using> does that. So for instance we can plot
+color-coded points:
+
+  seq 10 | feedgnuplot --with 'points pt 7 palette' --usingall '1:2:2'
+
+Here feedgnuplot read 1 column of data. It defauled to C<--tuplesize 2>, so it
+passed 2 columns of data to gnuplot. gnuplot then produced 3 values for each
+point, and plotted them as indicated with the C<points palette> style.
+
+=item
+
+You I<always> need a column of data to generate a curve. You might want to use a
+C<using> expression to plot a time series I<and> its cumulative integral. The
+C<using> expression can compute the integral, but you I<must> pass in the data
+twice; once for each curve to plot:
+
+  seq 100 |                           \
+    awk '{print $1,$1}' |             \
+    feedgnuplot                       \

+
+We just described how feedgnuplot parses its input data. When passing this data
+to gnuplot, each curve is sent independently. The domain appears in the leading
+columns followed by C<--rangesize> columns to complete each row. Without
+C<--domain>, feedgnuplot explicitly writes out sequential integers. gnuplot then
+knows how many values it has for each point, and it knows which style we're
+using, so it's able to interpret the data appropriately, and to make the correct
+plot.
+
+As an example, if gnuplot is passed 2 columns of data, and it is plotting C<with
+points>, it will use column 1 for the x coordinate and column 2 for the y
+coordinate. This is the default behavior, but the meaning of each column can be
+controlled via a C<using> expression in gnuplot (not feedgnuplot; keep reading).
+The default is sequential integers, so this example uses C<using 1:2> by
+default. We can flip the meaning of the columns by passing C<using 2:1>.
+Arbitrary expressions may be specified by enclosing each field in C<()>, and
+using C<$> to denote each data column. So to use the 2nd column as the x
+coordinate and the sum of the two columns as the y coordinate, C<using
+2:($1+$2)> is passed. Furthermore, the number of columns can vary. For instance
+gnuplot can read the same two columns of data, but produce a plot with the extra
+column encoding the sum as the color: C<using 1:2:($1+$2) with points palette>.
+Please see the gnuplot documentation for lots of detail.
+
+That's how I<gnuplot> works. Most of the time, I<feedgnuplot> doesn't pass any
+C<using> expressions at all, and gnuplot does the default thing. But if we want
+to do something fancy, feedgnuplot supports C<--using curveID expression> and
+C<--usingall expression>. So we can plot a parabola:
+
+  seq 100 | feedgnuplot --lines --usingall '1:($2*$2)'
+
+This is powerful, but there are some things to keep in mind:

+
+C<--using> overrides whatever C<using> expression feedgnuplot was going to pass.
+feedgnuplot passes a C<using> expression only if C<--histogram> or C<--timefmt>
+or C<--xticlabels> are given. So if C<--using> is given together with any of
+these, the user must take care to do the right thing (whatever that means at
+that time).
+
+=item
+
+The C<--tuplesize> controls the data passed to feedgnuplot and the data then
+passed to gnuplot. It does I<not> directly control how gnuplot eventually
+interprets the data: C<--using> does that. So for instance we can plot
+color-coded points:
+
+  seq 10 | feedgnuplot --with 'points pt 7 palette' --usingall '1:2:2'
+
+Here feedgnuplot read 1 column of data. It defauled to C<--tuplesize 2>, so it
+passed 2 columns of data to gnuplot. gnuplot then produced 3 values for each
+point, and plotted them as indicated with the C<points palette> style.

+You I<always> need a column of data to generate a curve. You might want to use a

+twice; once for each curve to plot:

+This is a tutorial and gallery demonstrating =feedgnuplot= usage. The
+[[https://github.com/dkogan/feedgnuplot/][documentation]] provides a complete reference, and [[https://github.com/dkogan/feedgnuplot/#recipes][application-specific usage
+examples]]. The capabilities of gnuplot itself are demonstrated at [[http://www.gnuplot.info/demo/][its demo page]].
+
+* Tutorial
+First, a trivial plot: let's plot a sinusoid
+
+#+BEGIN_SRC sh :results file link :exports both
+seq 100 | \
+perl -nE 'say sin($_/5.)' | \
+feedgnuplot
+#+END_SRC
+
+#+RESULTS:
+[[file:guide-1.svg]]
+
+This was a trivial plot, and was trivially-easy to make: we gave the tool one
+column of data with no specific instructions, and we got a plot.
+
+The interpretation of the input data is controlled by two arguments: ==--domain=
+and =--dataid=. Here we passed neither, so each line of input is interpreted as
+=y0 y1 y2...= with sequential integers (0, 1, 2, ...) used for the =x=
+coordinate. Let's pass in more than one =y= per line to plot a sine and a cosine
+together:
+
+#+BEGIN_SRC sh :results file link :exports both
+seq 100 | \
+perl -nE '$th = $_/100.*2.*3.14159;
+          $s  = sin($th);
+          $c  = cos($th);
+          say "$c $s"' | \
+feedgnuplot --lines --points
+#+END_SRC
+
+#+RESULTS:
+[[file:guide-2.svg]]
+
+Here I also passed =--lines --points= to make more legible plots.
+
+Note that, the lines may have different numbers of points. To plot the cosine
+from every line, but the sine from every 5th line:
+
+#+BEGIN_SRC sh :results file link :exports both
+seq 100 | \
+perl -nE '$th = $_/100.*2.*3.14159;
+          $s  = sin($th);
+          $c  = cos($th);
+          if($.%5) { say "$c";    }
+          else     { say "$c $s"; }' | \
+feedgnuplot --lines --points
+#+END_SRC
+
+#+RESULTS:
+[[file:guide-3.svg]]
+
+Each =y= is referred to as a "dataset" or "curve" in the code and documentation.
+
+With =--domain=, the =x= values are read from the data instead of simply
+encoding line numbers: each line of input is interpreted as =x y0 y1 y2...=.
+Let's plot =sin(theta)= vs. =cos(theta)=, i.e. a circle:
+
+#+BEGIN_SRC sh :results file link :exports both
+seq 100 | \
+perl -nE '$th = $_/100.*2.*3.14159;
+          $s  = sin($th);
+          $c  = cos($th);
+          say "$c $s"' | \
+feedgnuplot --lines --points --domain
+#+END_SRC
+
+#+RESULTS:
+[[file:guide-4.svg]]
+
+Hmmm. We asked for a circle, but this looks more like an ellipse. Why? Because
+gnuplot is autoscaling the =x= and =y= axes independently to fill the plot window.
+We can scale the axes /together/ by passing =--square=, and we get a circle:
+
+#+BEGIN_SRC sh :results file link :exports both
+seq 100 | \
+perl -nE '$th = $_/100.*2.*3.14159;
+          $s  = sin($th);
+          $c  = cos($th);
+          say "$c $s"' | \
+feedgnuplot --lines --points --domain --square
+#+END_SRC
+
+#+RESULTS:
+[[file:guide-5.svg]]
+
+Again, we can have multiple =y= in each line, and each line may have a different
+number of =y=. Let's plot a circle /and/ an ellipse, sampled more coarsely:
+#+BEGIN_SRC sh :results file link :exports both
+seq 100 | \
+perl -nE '$th = $_/100.*2.*3.14159;
+          $s  = sin($th);
+          $c  = cos($th);
+          if($.%5) { say "$c $s"; }
+          else     { $s2 = $s/2;
+                     say "$c $s $s2"; }' | \
+feedgnuplot --lines --points --domain --square
+#+END_SRC
+
+#+RESULTS:
+[[file:guide-6.svg]]
+
+We just plotted something where each point is represented by 2 values: =x= and
+=y=. When making 2D plots, this is the most common case, but others are
+possible. What if we want to color-code our points using another column of data?
+We feed in the new column, and we tell =feedgnuplot= that we now have /3/ values
+per point (the tuple size), and we tell =gnuplot= how we want this plot to be
+made. Color-coding by the angle, in degrees:
+
+#+BEGIN_SRC sh :results file link :exports both
+seq 100 | \
+perl -nE '$thdeg = $_/100.*360.;
+          $th = $_/100.*2.*3.14159;
+          $s  = sin($th);
+          $c  = cos($th);
+          say "$c $s $thdeg";' | \
+feedgnuplot --domain --square \
+            --tuplesizeall 3  \
+            --styleall 'with linespoints palette'
+#+END_SRC
+
+#+RESULTS:
+[[file:guide-7.svg]]
+
+Here we said that /all/ the datasets have 3 values per point. And that /all/ the
+datasets should be plotted with that particular style. The styles are strings
+that are passed on to =gnuplot= verbatim. So the full power of =gnuplot= is
+available, and there's nothing =feedgnuplot=-specific to learn. =gnuplot= has
+plenty of documentation about styling details.
+
+The above =--styleall= argument may be identically replaced with a shorthand:
+
+#+BEGIN_EXAMPLE
+--with 'points palette'
+#+END_EXAMPLE
+
+Note that the =--lines --points= specify the /default/ style only, so these
+options do nothing here, and if we want lines /and/ points, we ask for those in
+the style:
+
+#+BEGIN_EXAMPLE
+--with 'linespoints palette'
+#+END_EXAMPLE
+
+The styles and tuple sizes can be different for each dataset. For instance, to
+apply the colors only to the circle (dataset 0), leaving the ellipse (dataset 1)
+with the default tuple size and style:
+
+#+BEGIN_SRC sh :results file link :exports both
+seq 100 | \
+perl -nE '$thdeg = $_/100.*360.;
+          $th = $_/100.*2.*3.14159;
+          $s=sin($th); $c=cos($th);
+          if($.%5) { say "$c $s $thdeg" }
+          else     { $s2 = $s/2;
+                     say "$c $s $thdeg $s2"; }' | \
+feedgnuplot --lines --points --domain --square \
+            --tuplesize 0 3   \
+            --style     0 'with points palette' \
+            --legend    0 'circle' \
+            --legend    1 'ellipse'
+#+END_SRC
+
+#+RESULTS:
+[[file:guide-8.svg]]
+
+Here we also asked for dataset labels to make it clear to the viewer what's
+what.
+
+The other significant option involved in the interpretation of data is
+=--dataid=. This labels each dataset in the data, so instead of referring to
+dataset =0=, you could refer to dataset =circle=. With =--domain --dataid=, each
+line of input is interpreted as =x id0 y0 id1 y1...=, with the number of =y= in
+each dataset reflecting the tuple size. Naturally, =--dataid= without =--domain=
+is identical, except without the leading =x=. The previous plot can be
+reproduced with =--dataid=:
+
+#+BEGIN_SRC sh :results file link :exports both
+seq 100 | \
+perl -nE '$thdeg = $_/100.*360.;
+          $th = $_/100.*2.*3.14159;
+          $s=sin($th); $c=cos($th);
+          if($.%5) { say "$c circle $s $thdeg" }
+          else     { $s2 = $s/2;
+                     say "$c circle $s $thdeg ellipse $s2"; }' | \
+feedgnuplot --lines --points --domain --dataid --square \
+            --tuplesize circle 3   \
+            --style     circle 'with points palette' \
+            --autolegend
+#+END_SRC
+
+#+RESULTS:
+[[file:guide-9.svg]]
+
+Note that instead of labelling the datasets explicitly, we passed =--autolegend=
+to use the ID as the label for each dataset. This works without =--dataid= also,
+but the IDs are then the unhelpful sequential integers.
+
+Instead of identifying columns using explicit IDs inside the data stream (as
+with =--dataid=), it's possible to read [[https://www.github.com/dkogan/vnlog][vnlog]] data, which contains a single
+header line identifying the columns. For instance:
+
+#+BEGIN_SRC sh :results file link :exports both
+( echo '# th';
+  seq 100 | perl -nE 'say $_/100.*2.*3.14159;' ) | \
+vnl-filter -p 'c=cos(th),s=sin(th),th_deg=th*180./3.14159,s2=sin(th)/2' | \
+feedgnuplot --lines --points --domain --vnl --square \
+            --tuplesize s 3   \
+            --style     s 'with points palette' \
+            --legend s  circle \
+            --legend s2 ellipse
+#+END_SRC
+
+#+RESULTS:

+
+* Gallery
+This is a good overview of the syntax and of the data interpretation. Let's demo
+some fancy plots to serve as a cookbook.
+
+Since the actual plotting is handled by =gnuplot=, its documentation and [[http://www.gnuplot.info/demo/][demos]]
+are the primary reference on how to do stuff.
+
+** Line, point sizes, thicknesses, styles
+Most often, we're plotting lines or points. The most common styling keywords
+are:
+
+- =pt= (or equivalently =pointtype=)
+- =ps= (or equivalently =pointsize=)
+- =lt= (or equivalently =linetype=)
+- =lw= (or equivalently =linewidth=)
+- =lc= (or equivalently =linecolor=)
+- =dt= (or equivalently =dashtype=)
+
+For details about these and all other styles, see the =gnuplot= documentation.
+For instance, the first little bit of the docs about the different line widths:

+ Each terminal has a default set of line and point types, which can be seen
+ by using the command `test`.  `set style line` defines a set of line types
+ and widths and point types and sizes so that you can refer to them later by
+ an index instead of repeating all the information at each invocation.

+       set style line <index> {{linetype  | lt} <line_type> | <colorspec>}

+gnuplot has a =test= command, which produces a demo of the various available
+styles. This documentation uses the =svg= terminal (what gnuplot calls a
+backend). So for the =svg= terminal, the various styles look like this:
+
+#+begin_src gnuplot :results file link :exports both :file gnuplot-terminal-test.svg
+test
+#+end_src
+
+#+RESULTS:

+
+So for instance if you plot =--with 'linespoints pt 4 dt 2 lc 7'= you'll get a
+red dashed line with square points. By default you'd be using one of the
+interactive graphical terminals (=x11= or =qt=), which would have largely
+similar styling.
+
+Let's make a plot with some variable colors and point sizes:
+
+#+BEGIN_SRC sh :results file link :exports both
+seq -10 10 | \
+perl -nE '$, = " ";
+          say "parabola", $_*$_, abs($_)/2, $_*50;

+Here we used =--set= to set the range of the colorbar. =--set= (and =--unset=)
+map to the gnuplot =set= (and =--unset=) command.

+** Error bars
+As before, the =gnuplot= documentation has the styling details:

+gnuplot -e 'help xerrorbars'
+gnuplot -e 'help yerrorbars'
+gnuplot -e 'help xyerrorbars'
+#+END_SRC

+For brevity, I'm not including the contents of those help pages here. These tell
+us how to specify errorbars: how many columns to pass in, what they mean, etc.

+** 3D plots
+We can plot in 3D by passing =--3d=. When plotting interactively, you can use

+Unlike 2D plots, 3D plots have a 2-dimensional domain, and =--domain= is
+/required/. So each line is interpreted =x y z0 z1 z2...=.

+** Histograms
+=gnuplot= (and =feedgnuplot=) has support for histograms. So we can give it
+data, and have it bin it for us. Pre-sorting the data is unnecessary. Let's look
+at the central limit theorem: we look at the distribution of sums of 10 uniform
+samples in [-1,1]: it should be normal-ish. And let's draw the expected perfect
+PDF on top (as an equation, evaluated by =gnuplot=).

+#+BEGIN_SRC sh :results file link :exports both

+Nsum=10;

+
+If we want multiple histograms drawn on top of one another, the styling should
+be adjusted so that they both remain visible. Let's vary the size of the sum,
+and look at the effects: bigger sums should be more gaussian-like:

+#+BEGIN_SRC sh :results file link :exports both
+N=20000;

+** Labeled bar charts
+=feedgnuplot= supports bar charts to be drawn with labels appearing in the data.
+These aren't "histograms", where gnuplot bins the data for us, but rather the
+data is given to us, ready to plot. We pass =--xticlabels= to indicate that the
+x-axis tic labels come from the data. This changes the interpretation of the
+input: with =--domain=, each line begins with =x label ....=. Without
+=--domain=, each line begins with =label ...=. Clearly, the labels may not
+contain whitespace. This does /not/ affect the tuple size.
+
+Basic example without =--domain=:
+
+#+BEGIN_SRC sh :results file link :exports both
+echo "# x label a b
+       5  aaa   2 1
+       6  bbb   3 2

+            --ymin 0 --unset grid
+#+END_SRC
+
+#+RESULTS:
+[[file:guide-21.svg]]
+
+We can also pass =--domain= to read the =x= positions from the data also:
+
+#+BEGIN_SRC sh :results file link :exports both
+echo "# x label a b
+       5  aaa   2 1
+       6  bbb   3 2
