Re: [Matplotlib-users] 2 possible bugs with make_axes_area_auto_adjustable
I noticed what is causing one of these issues: 1) When I point-pick on the plot, the plot area still jumps (expands vertically a small amount). It used to do this each time I point-picked, but after upgrading MPL it now just does it the *first* time only. But is it possible it can be fixed so it doesn't jump at all? I see why this happens. When I point pick, a popup window pops up and covers the plot. I think this triggers a redraw. What causes the jump in my case is that the plot's title is set, in y coordinate, to 1.04. That is, the line is this: self.subplot.title.set_y(1.04) This is interacting with the line in make_axes_area_auto_adjustable: if self.title.get_visible(): artists.append(self.title) Essentially, it is getting the bbox, taking into consideration the plot's title and other artists. But if the title is set to greater than 1.00, when I point pick (and force a redraw?), it has to recalculate the plot's axes areas and it adjusts things, so the user sees the small vertical expansion (jump). The problem goes away if I set the plot's title to 1.00: self.subplot.title.set_y(1.00) *However, this puts the title too close to the top of the plot area for my aesthetic liking.* I'd prefer a little larger margin. There should be a simple fix that allows for the title to be a bit higher off the plot area and yet not cause this jump. It would be in the code at the end of this email, but i don't know enough about bbox to fix it yet...any hints?

[Matplotlib-users] 2 possible bugs with make_axes_area_auto_adjustable
Jae-Joon's code, make_axes_area_auto_adjustable has been a great help to dynamically resizing my plots' axes area--such an improvement. But there are two bugs I've noticed that I wonder if has been identified/fixed yet: 1) When I point-pick on the plot, the plot area still jumps (expands vertically a small amount). It used to do this each time I point-picked, but after upgrading MPL it now just does it the *first* time only. But is it possible it can be fixed so it doesn't jump at all? 2) I just noticed that if a plot is resized so that the window that the plot is embedded in is *narrower than the title on the plot*, the resizing of the axes area gets very messed up (it gets *much8 narrower than is necessary to fit the available area). I'm not sure what the best approach to fixing this is, since it's not ideal to have a title not fit the figure's area, either...is it possible to flow-wrap a plot title?
