title: Python Pyplot: How to scale x-axis independant from number of list-elements?
body: <p>Just want to plot a list with 50 (actually 51) elements: The list indices from 0 to 50 should represent meters from 0 to 10 meters on the x-axis, while the index of every further element increases by 0.2 meters. 
  Example:</p>
  
  <pre><code>list = [2.5, 3, 1.5, ... , 7, 9]
  len(list)
  &gt;&gt;50
  </code></pre>
  
  <p>I would like the x-axis plotted from 0 to 10 meters, i.e. 
  (x,y)==(0, 2.5), (0.2, 3), (0.4, 1.5), ..., (9.8, 7), (10, 9)</p>
  
  <p>Instead, the list is obviously plotted on an x-scale from 0 to 50.
  Any idea how to solve the problem? Thanks!</p>
