title: How to smooth matplotlib contour plot?
body: <p>I have numpy array with this shape: (33,10). When I plot contour I get ugly image like this:

  <p>while <code>contour()</code> doesn't seem to have any argument about smoothing or some sort of interpolation feature.</p>
  
  <p>I somehow expected that tool which offers contour plot should offer smoothing too.<br>
  Is there straight forward way to do it in MPL?</p>
