Came across an oddity here in one of the demos:
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.
