title: Add multiple Figures in matplotlib with PyQt
body: <p>I was designing my GUI with QtDesigner and PyQt4. First in QtDesigner I added a matplotlib widget to my GUI. Then in the code I want to add multiple embedded figures to be displayed in parallel.</p>
  
  <p>I checked the given code of the MatplotlibWidget class that comes with PyQt4. It uses the following code to create Figure.</p>
  
  <pre><code>self.figure = Figure(figsize=(width, height), dpi=dpi)
  Canvas.__init__(self, self.figure)
  </code></pre>
  
  <p>But when I check how to add more figures, most of the solution online is using the </p>
  
  <pre><code>pyplot.figure()
  </code></pre>
  
  <p>But this is not suitable for my case, since it creates standalone dialog. I want the new figure to be embedded in my current GUI.</p>
  
  <p>Any one knows how to add new figures without using the pyplot?</p>
