hello All
have you never tried to embed a matplotlib 3d graph inside pyqt ?
i'm tring to do it .. but i've problenms to refresh my plot.
The 3d data are displayed ok inside a pyqt simple widget,
but if i try to redraw the image (re-call the on_draw function) ...
i have it overlay the previouse one.
If i add "clear()" at begin of my "on_draw" action,
the plot is update correctly ... and each "on_draw" action give me the correct results ...
but then i'm no more able to move the 3d plot view (but i can only zoom in/out the scene)
the code i'm using is : [http://paste.debian.net/106890](http://paste.debian.net/106890)
at line 22 there is a "def erase(self):" function
if i connect it to the plot i have the image is correctly redraw .. but then i lost the 3d actions
can you give it a try ?
seems thast the "clear()" action broke something ... thanks a lot for any help
to try it .. i've upload the .mat file (just few kbytes)
it is available at :

Thank you!
Massimo.
ok 
i find a solution … maybe correct :
in the init i added :
self.a = None
then in “on_draw” :
if self.a is not None:
self.axes.collections.remove(self.a)
self.a = self.axes.plot_surface(x, y, z, rstride=res, cstride=res, facecolors=colors)
now the plot is refreshed ok
