Try using the FLTK toolkit, just to see if plotting in general works.


graphics_toolkit fltk
hist (rand (10, 1))


Given the error messages, this seems to be a packaging/distribution error in that the version of Octave you have doesn't include gnuplot (a separate program).

Dom, what do you think could be the reason for this message?


/bin/sh: gnuplot: command not found


Please check if gnuplot is installed and working.

hist command fails... looks like a missing library:


octave:1> hist (rand(10,1))
error: popen2: popen2 (child): unable to start process -- No such file or directory
error: called from:

/bin/sh: gnuplot: command not found
