Re: Printing a figure as a png... This should be basic!

[Pavel Schor]

Hi, I had same problem, in my case it was missing library. I mentioned
my solution here  2 months ago:

in octave3.2  with gnuplot 4.2.5 on ubuntu 9.04 I was not able to save
plot as .png image.... Problem was in missing library libgd. I
downloaded it from www.libgd.org, and then I have recompiled gnuplot.
After that everything is OK.
