Details:

Consider the following code:


x = 1:10;
plot(x,3*sqrt(x),";First;",x,2*sqrt(x),";Second;",x,sqrt(x),";Third;");
print("test.eps","-deps2","-mono","-debug");


Using Octave 3.2.3 as shipped with ubuntu 10.04, I get that the three curves
have different linestyle (see attached test.eps.good). Using octave 3.6.1
(which I compiled myself, again under ubuntu 10.04), I get all solid lines
(see attached test.eps.bad) both with the gnuplot and with the fltk backend.
At the moment I cannot check if this happens with a recent tip also.

Looking at octave-print-commands.log which is produced by the "-debug" option
above, I see that Octave 3.2.3 inserts this:


set style line 1 default;
set style line 1 linewidth 0.500000 pointsize 1.000000;
set style line 2 default;
set style line 2 linewidth 0.500000 pointsize 1.000000;
set style line 3 default;
set style line 3 linewidth 0.500000 pointsize 1.000000;


while Octave 3.6.1 inserts this:


set style line 1 default;
set style line 1 linetype 1 linewidth 0.500000;
set style line 2 default;
set style line 2 pointsize 2.000000;
set style line 2 default;
set style line 2 linetype 1 linewidth 0.500000;
set style line 3 default;
set style line 3 pointsize 2.000000;
set style line 3 default;
set style line 3 linetype 1 linewidth 0.500000;
set style line 4 default;
set style line 4 pointsize 2.000000;


The problem seems caused by the fact that all styles are defined with
"linetype 1" (there are also redundant "set style line X default").
I can get the old behavior by manually setting the line styles as follows:


x = 1:10;
plot(x,3*sqrt(x),"-;First;",x,2*sqrt(x),"--;Second;",x,sqrt(x),":;Third;");
print("test.eps","-deps2","-mono","-debug");
