title: matplotlib figure still internally uses screen size after using figsize
body: <p>I'm using <code>plt.figure(figsize=(width, height))</code> to adjust the size and aspect ratio of the window that is generated when showing a plot. 
  However, my tick annotations on the vertical axis are very long so that they disappear from the window. But, lo and behold, they <em>do</em> fit on my screen if I then manually adjust the window size to my screen size.</p>
  
  <p>It thus seems that although you can manually modify the window size using the <code>figsize</code> option, <code>matplotlib</code> still generates the figure as if you were going to use it in a maximized window. How can I change the figure size that is used internally? (What should I do to make <code>matplotlib</code> resize the image so it actually fits in the window I have defined?)</p>
