Re: Fwd: can not get octave to plot - posting again

[Nasreddin Hodja]

Thank you for your responses. Ben's suggestion actually makes an empty plot box pop - I did not have that before... But the plot window is blank and the error I get is still the same.

octave-3.2.2:1> setenv ("GNUTERM", "x11")
octave-3.2.2:2> plot(1:10)

error: __gnuplot_get_var__: Can not make fifo (No such file or directory)
error: called from:
error:   /Applications/Octave.app/Contents/Resources/share/octave/3.2.2/m/plot/__gnuplot_get_var__.m at line 69, column 7

I tried Leo's suggestion as well...Created a .octaverc and pasted the line: gnuplot_binary("/Applications/Gnuplot.app/Contents/Resources/bin/gnuplot") 
in it. The behavior is the same. So I assume location of gnuplot is known by octave, but not really sure... When I do not type  setenv ("GNUTERM", "x11") I do get a pop up blank plot window but when I do, again the error is:

octave-3.2.2:1>        setenv ("GNUTERM", "x11")
octave-3.2.2:2> plot(1:10)
error: __gnuplot_get_var__: Can not make fifo (No such file or directory)

error:   /Applications/Octave.app/Contents/Resources/share/octave/3.2.2/m/plot/gnuplot_drawnow.m at line 88, column 5

just to check at the end:
octave-3.2.2:3> gnuplot_binary
ans = /Applications/Gnuplot.app/Contents/Resources/bin/gnuplot


Any other thoughts?

Thanks,

I think this error indicates octave cannot find gnuplot. You can tell
octave the location of gnuplot by putting

gnuplot_binary("path to gnuplot");

in your .octaverc file in your home directory.
