title: Is there a way to tell matplotlib to loosen the zoom on the plotted data?
body: <p>I have some data plotted which includes some limits on each subplot: <img src="https://i.stack.imgur.com/mRdW1.png" alt="aerodynamic angles with limits"> Both axes have the limits, but since the data fits so nicely within the limits on the second plot, the limits themselves set the boudaries for the y-axis, making them invisible.</p>
  
  <p>To make them visible, I could do something like this:</p>
  
  <p><code>axes.set_ylim(1.1*lowerLimit,1.1*upperLimit)</code> </p>
  
  <p>where <code>lowerLimit</code> and <code>upperLimit</code> are the data used to generate the limits in the first place, but I am wondering if matplotlib has a mechanism to tell it to not be so zealous in it's automatic setting of the limits.  The solution I have now also has the limitation that if the data deviates from the boundaries, it risks going outside the lines, so I searched for a complement to <code>set_ylim()</code> which would tell me what the limits are, somehting like <code>get_ylim()</code> but it does not seem to exist in <a href="http://matplotlib.sourceforge.net/api/axis_api.html" rel="nofollow noreferrer">the documentation</a>.</p>
  
  <p>Thanks for your help.</p>
