title: Set points outside plot to upper limit
body: <p>Maybe this question exists already, but I could not find it. </p>
  
  <p>I am making a scatter plot in Python. For illustrative purposes, I don't want to set my axes range such that all points are included - there may be some really high or really low values, and all I care about in those points is that they exist - that is, they need to be in the plot, but not on their actual value - rather, somewhere on the top of the canvas.</p>
  
  <p>I know that in IDL there is a nice short syntax for this: in <code>plot(x,y&lt;value)</code> any value in y greater than <code>value</code> will simply be put at <code>y=value</code>.</p>
  
  <p>I am looking for something similar in Python. Can somebody help me out?</p>
