title: Plot a barchart after pandas.value_counts()
body: <p>I have a dataframe with several columns and I need to plot a graph based on the number of counts in the 'Total'column.</p>
  <p>I performed the following code:</p>
  <pre><code>df['Total'].value_counts()
  </code></pre>
  <p>The output are as follows:</p>
  <pre><code>2   10
  20  15
  4   8
  8   20
  </code></pre>
  <p>This means the the number 2 appears in the Total columns 10 times, number 20 appears 15 times and so on.</p>
  <p>How do I plot a barchart with the x-axis as the number itself and the y-axis as the occurances and in ascending
  order? The x-axis will plot 2 -&gt; 4 -&gt; 8 -&gt; 20.
  What are the next steps after:</p>
  <pre><code>%matplotlib inline
  import matplotlib.pyplot as plt
  </code></pre>
