[PyQt] refresh 3dplot

[Massimo Di Stefano]

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 :-)
