title: How to produce a multiple group bar chart based on a specific dataframe column
body: <p>I have a dataframe which has the following data:</p>
  <pre><code>Age A
  5   True
  5   True
  10  False
  15  False
  15  True
  20  False
  25  True
  </code></pre>
  <p>How can I make a bar chart plot which has the values of the total number of rows in Age? So for example, 7 as the Y axis and the age as the X axis, with each Age having a True/False bar plot.</p>
  <p>I would like something like this, however instead of it saying gender F/M, it does True/False, for each Age range:</p>
