title: Has anyone Compared Qt Commercial Charts with matplotlib?
body: <p>What is better to use for interactive data plotting?
  matplotlib (<a href="http://www.matplotlib.org" rel="nofollow">http://www.matplotlib.org</a>) or Qt Commercial Charts (<a href="http://qt.digia.com/Product/Qt-Add-Ons/Charts/" rel="nofollow">http://qt.digia.com/Product/Qt-Add-Ons/Charts/</a>) 
  There are several functionality missing from matplotlib with regards to interactiveness like when I want to hover and display information specific related to the points in a scatter plots.
  My overall program is in python and pyqt.
  I also had a look at pyqtgraph.org but I dont think it is mature enough.</p>
