title: Custom chart type with matplotlib
body: <p>Is it possible to draw completely different chart types then predefined?</p>
  
  <p>I searched through the existing types and was unable to find a suitable one.</p>
  
  <p>In general, I need to build smth</p>
  
  <p>like a "bar and wisher" candle (like Excel has)
  but with numbers on top and bottom plates (deviation errors)</p>
  
  <p>Thanx.</p>
