How to put the title at the bottom of a figure in matplotlib?
<p>I use matplotlib to plot a figure with four subfigures, and <code>set_title</code> method put the title ( <code>(a) (b) (c) (d)</code>) on the top of every subfigure, see the following code example.  </p>

<p><code>
fig = pyplot.figure()<br>
ax = fig.add_subplot(1, 4, 1)<br>
ax.set_title('(a)')
</code></p>

<p>But I want to put every title at the bottom of every subfigure. I can't figure out it by the matplotlib document and google. So I need your help, thanks very much.</p>
