Aha -- here from John (in another thread) is why those lines were commented out: """" On Sun, Jul 27, 2008 at 4:24 PM, John Hunter <jd...@gm...> wrote: > > if midPoint: > > if self.gridOn: > > self.gridline.draw(renderer) > > if self.tick1On: > > self.tick1line.draw(renderer) > > if self.tick2On: > > self.tick2line.draw(renderer) > For a little extra color on what is going on here -- we don't want to automatically clip the tick lines to the axes bounding box because someone might choose the tick direction 'out'. Since we can't use graphical clipping, this test is trying to make sure the tick location is in the view interval before drawing it. You may want to consider a overridable method 'is_draw_tick' or something along those lines, which defaults to:: mtransforms.interval_contains(self.get_view_interval(), self.get_loc()) """" So, I suppose we'll need to find another solution other than graphical clipping, or a way to do it only when needed to solve the problem at hand (in this thread).
