title: rescale and normalize x axis numbers in python3.2 and matplotlib
body: <p>I am working in python 3.2 and matplotlib. </p>
  
  <p>The numbers of x-axis are between 0 and 1000000. </p>
  
  <p>In my plot, the numbers of x-axis are long and overlap each other. </p>
  
  <p>I want to re-scale and normalize them between 0 and 10 and also show the unit (such as 10^6) around the x-axis. </p>
  
  <p>How can I do that?</p>
  
  <p>Any help would be appreciated. </p>
