Question

I\'m using Octave 4.0.0 on a fresh Windows 10 installation and the graphics toolkit related functions (such as plot() or hist()) are simply not wor

Answer 1

I have 4.2.0 running on Windows 7. The first time plot takes about a couple of minutes and its faster from then on. The toolkit is "qt".

Answer 2

The first time you use plot, imagesc, or something else that uses plotting functions it will cause Octave to hang for a while (potentially minutes). It may be quicker to plot a small dataset with plot([1 2 3 4]) initially.

After the initial plot, subsequent ones should be quick, even if you reopen Octave or reboot your computer.

This happens consistently using Octave is 4.0.0-4.0.2, and potentially in other versions on Windows 10.

Answer 3

Your PC needs to be installed gnuplot separately from SourceForge as Octave gets some errors while installing itself in W8/10.

Here is the link attached. https://sourceforge.net/projects/gnuplot/?source=directory

You don't need to change any installation files.

This should work
