title: how to create a bar chart with matplotlib using table data
body: <p>The idea is quite simple: I want to create a bar chart with matplotlib using data of a table that is being generated before. </p>
  
  <p>I expect a chart like this one: </p>

  <p>But Im wondering how to do this just by using data out of a dbf table instead. </p>
  
  <p>It seems to be somehow possible but even this example I didn't get to work:  </p>

  <p>As I am a beginner with matplotlib I would like to learn this using a functioning example. </p>
  
  <p>1) Are there any examples or code snipplets around to look at that any of you could recommend?</p>
  
  <p>2) What data format would be best for this task (my tool generates dbf, but it's probably not a big deal to convert either to csv or Excel) </p>
