title: How do I display real-time graphs in a simple UI for a python program?
body: <p>I have a complicated algorithm that updates 3 histograms that are stored in arrays.  I want to debug my algorithm, so I was thinking of showing the arrays as histograms in a user interface.  What is the easiest way to do this.  (Rapid application development is more important than optimized code.)</p>
  
  <p>I have some experience with Qt (in C++) and some experience with matplotlib.</p>
  
  <p>(I'm going to leave this question open for a day or two because it's hard for me to evaluate the solutions without a lot more experience that I don't have.  Hopefully, the community's votes will help choose the best answer.)</p>
