A few weeks ago I reported a double draw problem in the qt backends. They both have a draw() method that looked like this:
def draw( self ): self.replot = True FigureCanvasAgg.draw(self) self.repaint( False ) It turned out that FCA::draw() and self.repaint() both did a draw which slowed everything down. Commenting out the FCA draw call seemed to work fine: def draw( self ): self.replot = True self.repaint( False ) However, this breaks when running code like this: import pylab as p p.plot( [1,2,3] ) p.savefig( 'image.png' ) The image is never drawn in this case. If you do a show() and save the image from the gui, then everything is fine. I did some experimenting and the solution may be to do this: def draw( self ): self.replot = True FigureCanvasAgg.draw(self) Which does seem to work for the cases I have. Could someone else take a look and see if this doesn't break anything (You'll have to edit your local backends, I haven't changed anything).
