Alan, I've fixed the issue with p11. p14 does not display properly for me (for reasons I don't understand). The axes rather than the mesh are animated. It works fine if called directly from octave in the bindings/octave directory so it is something about the way the test script works. I've changed example 12 so that you no longer have to press a button in example 20 to get the last plot (was this your issue?) All other xwin examples are fine - I do not see your issues with 19 or 21. Which version of octave are you using? I have tested with 3.2. For qtwidget those examples which rely on calling plGetCursor (12, 17, 18) fail as qtwidget does not support this. Otherwise qtwidget works as for xwin. > > You have only mentioned -dev tk in passing so I thought I had better mention > that your fix to the script still leaves -dev tk crashing immediately for p1 > for me.

The current build system certainly does not generate octave bindings for these, hence the failure. I've commented out these extensions and octave now works with just the standard tk driver again. Results are comparable to the xwin driver since tk support plGetCursor. I don't propose to do anything more with the tk support since I don't fully understand it, I don't use it, and clearly no-one else does with tk or they would have filed a bug report a long time ago. > > I think a lot of the other issues are to do with the interactive aspects. > > Only the xwin and tk drivers support xor mode which is required.

Could that example 1 option be made into a more > convincing demonstration of xor capability? I'll try and check this out too.
