title: how to export to pdf a graph based on a pandas dataframe?
body: <p>I have a pandas dataframe and I am using the useful .plot() method.</p>
  
  <p>The dataframe looks like</p>
  
  <pre><code>col1   col2   col3
  1      2      3
  7      0      3
  1      2      2
  </code></pre>
  
  <p>I therefore use <code>df.plot()</code> to get the chart I want.</p>
  
  <p>Problem is, I would like to export the chart to a pdf. Ideally, I could also generate other charts (based on this dataframe) and add them to the pdf. </p>
  
  <p>It is possible to do so ?
  Thanks!</p>
