  <p>I'm a newbie to Matplotlib and have encountered this problem. I'm using a Ubuntu system. I started with Matplotlib 0.99 and realized that I really need the new feature of "triplot" in the newer versions. So I downloaded the newest version by</p>
  
  <pre><code>git clone git://github.com/matplotlib/matplotlib.git
  </code></pre>
  
  <p>and installed it. However, when I work with python interactively, <code>pyplot.show()</code> does not show me the figure I plot, nor did it responded with any error message. <code>pyplot.show()</code> did work in the old version of matplotlib 0.99.</p>
  
  <p>To be more specific, I seemed to have no problem importing "matplotlib" or modules inside the package; I can generate pdf files of a bunch of figures, but I just can't have the figure show up by typing <code>pyplot.show()</code> at the end of my code. Can anyone help me? Thank you!</p>
