`gaplot`

Defines a plot of

versus `y`

, or
`x`

versus `z`

and `x`

, to be
produced through the external "gnuplot" program, if that program is
available.
`y`

The call without any arguments constructs the plot based on all
preceding `gaplot`

calls that haven’t produced a plot yet.

Compare gplot.

If only one of

, `x`

, `y`

are
specified, then it is interpreted as `z`

and provides the y
coordinates of the data points to plot, with default x coordinates.
If `y`

and `x`

are specified, then they must
have the same dimensional structure. Then the x coordinates are taken
from `y`

and the y coordinates are taken from
`x`

. If `y`

, `x`

, and `y`

are specified, then all three must have the same dimensional structure
and provide the x, y, and z coordinates of the points to plot.
`z`

is a positive integer that selects the line type.
`ltype`

is a positive integer that selects the point type.
`ptype`

is a positive integer that selects the dash type.
Depending on which of these are specified, you get a graph showing
lines, symbols, or both.
`dtype`

is text specifying which color to use.
`color`

specifies the text with which to identify the
graph in the legend in the plot.
`legend`

provides the title for the x axis.
`xtitle`

provides the title for the y axis.
`ytitle`

provides the title for the y axis.
`ztitle`

provides the main title, displayed above the plot.
`title`

Mode parameters `/lii /loi /lio /loo`

specify whether the x and y
axes are linear (`i`

) or logarithmic (`o`

) for the x (first
`i`

or `o`

) and y (second `i`

or `o`

) axes. Mode
parameters `/liii /loii /lioi /looi /liio /loio /lioo /looo`

similarly specify for the x, y, and z axes.
