title: Changing plot scale by a factor in matplotlib
body: <p>I am creating a plot in python. Is there a way to re-scale the axis by a factor? The <code>yscale</code> and <code>xscale</code> commands only allow me to turn log scale off. </p>
  
  <p><em>Edit:</em><br>
  For example. If I have a plot where the <code>x</code> scales goes from 1 nm to 50 nm, the x scale will range from 1x10^(-9) to 50x10^(-9) and I want it to change from 1 to 50. Thus, I want the plot function to divide the x values placed on the plot by 10^(-9)</p>
