Vertical spacing between xticklabel to the bottom of x-axis
<p>I am wondering if there could be any way to change the spacing between xticklabel (i.e. $\widetilde{M}) and the bottom of x-axis? In my case the spacing is too small so that the tilde above M (left bar) becomes invisible. BTW I am using pandas' plot function to generate the bar plot.</p>

<p>Assuming you <code>import matplotlib.pyplot as plt</code> You can manipulate the pyplot object via the tick_params method and <code>pad</code> arg. E.g.:</p>

<pre><code>plt.tick_params(pad=10)
</code></pre>
