Came across an oddity here in one of the demos: http://matplotlib.sourceforge.net/mpl_toolkits/mplot3d/tutorial.html#subplotting
In the second subplotting example, there is supposed to be a y-axis label, but it is being cut off. In this example, I used plt.figaspect() to set an appropriate figure aspect for a 2x1 subplot grid. However, it looks like it sets the figure too narrow. The aspect ratio has to be set to around 1.05 before the entire y-axis label appears. I don’t know if this is a bug or not, but I thought I ought to raise this issue.
