Currently, I use print -dpng foo.png to print a plot to file in Octave 3.0.1 on Ubuntu.
Sometimes, I generate thousands of images in a loop.
Whenever a new image pops up, it grabs the mouse control precluding me from multitasking.
Is there anyway to print silently or quietly?
It would be easier to answer your question with a little more information about what you are doing. But with a little guessing maybe this is what you need:
f = figure
set(f, "visible", "off")
plot([1,2,3,4])
print("MyPNG.png", "-dpng")
