title: why do i get ValueError: width and height must each be below 32768 after annotations?
body: <p>I'm getting very confused by this error, because I'm running a code that was working on the same data I've already used.
  The only thing I changed was adding these two lines to annotate different areas of the plot:</p>
  
  <pre><code>plt.annotate('first group',xy=(100000, position1),size='x-large',ha='center',va='top',bbox=dict(alpha=0.5,facecolor='white',boxstyle='round'))
  plt.annotate('second group',xy=(100000,NOJU[10]['n0/'][-1000]),size='x-large',ha='center',va='top',bbox=dict(alpha=0.5,facecolor='white',boxstyle='round'))
  </code></pre>
  
  <p>where 100000 is half of the length of the x axis. If i delete these lines I don't get the error anymore, how is this possible? I have no clue and I need to annotate the plot...</p>
  
  <p>Thank you!</p>
