plot directly to postscript with Octave2.9 on low end server

[Dieter Jurzitza]

Dear Jacco,
there is only one way IMHO:

write the data you want to plot into a file (for example) "dummy.dat" 
containing (for example) x - y values, e.g.

0 0
1 1
2 4
3 9

for y=x**2. The file can be handled very much like in "C", fopen will open it, 
fprintf can write to it etc .... 
Then write a plt-file dummy.plt with the following contents (or similar):

#!/usr/bin/gnuplot
set terminal postscript enhanced color solid linewidth 2 "Arial, 12"
set output "dummy.ps"
plot "dummy.dat" using 1:2 w l
set output
set terminal

make it executable system("chmod 0755 dummy.plt") and execute "dummy.plt" with 
a system command from within octave (system(dummy.plt)). This should result 
in a postscript file "dummy.ps" in your working directory.
Hope this helps,
take care



Dieter

if you really want to see the pictures above - use some font
