title: How to increase font size of bottom bar MPAndroidChart
body: <p>I have a MPAndroidChart BarChart and I have looked through the javadoc and online documentation but am unable to find a way to increase the size of the text at the bottom of the chart.</p>
  
  <p>Here is an image which shows the chart and the font at the bottom left which is too small to view properly on this higher resolution tablet. Is there a way to increase this font size?</p>

  <p>Note: I recognize that increasing the axis label size is done with:</p>
  
  <pre><code>chart.getXAxis().setTextSize(20);
  </code></pre>
  
  <p>Edit: I have searched online at a variety of topics and looked through the MPAndroidChart github project but have been unable to find code to make this change. I have been able to change all the other font sizes so can only assume this must also be possible.</p>
