From: David Just [mailto:just.da...@mayo.edu] Sent: Friday, August 12, 2011 11:05 Now that I'm pre-building all my enlarged interpolated images to scroll through, I'm having trouble forcing the figure/FigureCanvas to be the size I want. I'm trying: fig.set_size_inches(768 / 72.0, 768 / 72.0), but it ends up the same size as the default plot. If the issue is that the GUI window is not changing size, try adding "forward=True" to the set_size_inches call. Developers: As I was checking this with v. 1.0.1, I noticed that the Qt4Agg and TkAgg backends are inconsistent in how they set the size of a figure. Here is the Qt4Agg behavior: >>> fig = plt.figure(figsize=[6, 4]) >>> print fig.get_size_inches() [ 6. 3.97916667] >>> fig.set_size_inches([6, 4], forward=True) >>> print fig.get_size_inches() [ 6. 3.4375] The initial figure size isn't quite right, and the size after set_size_inches is worse. (Is the resize ignoring the toolbar height?) Here is the TkAgg behavior: >>> fig = plt.figure(figsize=[6, 4]) >>> print fig.get_size_inches() [ 6.125 4.125] >>> fig.set_size_inches([6, 4], forward=True) >>> print fig.get_size_inches() [ 6. 3.64583333] Again, the initial size is off (due to the window border?), and the resized size is incorrect (toolbar again?). The WXAgg backend correctly sets the figure canvas to the desired size: >>> fig = plt.figure(figsize=[6, 4]) >>> print fig.get_size_inches() [ 6. 4.] >>> fig.set_size_inches([6, 4], forward=True) >>> print fig.get_size_inches() [ 6. 4.] I didn't check any other backends. I didn't see any indication in the master branch that this behavior has changed since 1.0.1. I didn't find a report for this issue on the tracker; shall I create one?
