title: Figure text in matplotlib
body: <p>I'm plotting quite simple with</p>
  
  <pre><code>plt.plot(a,b)
  plt.grid()
  plt.show()
  </code></pre>
  
  <p>But I need a figure text. I know I can use <code>text(x, y, my_text)</code> but I don't always know which combinations of <code>x</code> and <code>y</code> are visible in the plot due to different plot values.</p>
  
  <p>Can I instead place the text below the plot? I guess it's something like</p>
  
  <pre><code>fig = plt.figure()
  fig.text(0,0,my_text)
  fig.plot(a,b)
  </code></pre>
