[Gnuplot-info] Plots missing in multiplot using pslatex terminal with macros.

[Colin A. <ca...@uw...>]

Hello,

I'm trying to create a multiplot with ten subplots using the pslatex
terminal.  My multiplot block looks something like the following:

---- <begin code> ----
set terminal pslatex color size 16cm,23cm
set output 'multiplot.tex'

set style data histograms
set style fill solid noborder
set style histogram clustered gap 3
set nokey

set multiplot
set size 0.5,0.2

set title 'Plot 1'
set origin 0.0,0.8
plot 'datafile1.txt' using 2 notitle with histograms linecolor rgbcolor
"black", '' using 3 notitle with lc rgbcolor "grey60"

set title 'Plot 2'
set origin 0.5,0.8
plot 'datafile2.txt' using 2 notitle with histograms linecolor rgbcolor
"black", '' using 3 notitle with histograms linecolor rgbcolor "grey60"

set title 'Plot 3'
set origin 0.5,0.8
plot 'datafile3.txt' using 2 notitle with histograms linecolor rgbcolor
"black", '' using 3 notitle with histograms linecolor rgbcolor "grey60"
.
.
.
unset multiplot

---- <end code ----

where, for brevity, I've omitted the definitions for Plots 4 through 10.

When I run this using gnuplot (v4.2 patchlevel 4), the last eight plots
have only plot titles and axes labels --- no histograms.  The problem
stems from specifying  linecolor on the plot command:

1. Specifying a linecolor on one plot command is O.K..  All ten plots
are correctly drawn.

2. Specifying a linecolor on two plot commands causes problems.  All
plots after the second plot command containing a linecolor specification
have only plot titles and axes labels drawn.

So, if I specify a linecolor on the first and second plot commands, the
first two plots are fully drawn.  If I specify a linecolor on the first
and third plot commands, the first three plots are fully drawn.  The
rest of the plots have only plot titles and axes labels.

Other terminals I've tried (i.e., postscript and emf) behave properly.

Does anyone have some insight into the cause of the problem and how to
fix it?

Until next time, Colin.
