title: matplotlib using twinx and twiny together (like twinxy)
body: <p>Can I have both twinx and twiny together (i.e. something like twinxy)?
  I want to put a CDF on a bar plot where the X axis of the bar plot is in log-scale. I cannot make the Ys together, because the bar plot y range is very large comparing [0,1] for CDF.</p>
  
  <p>Any ideas?</p>
  
  <p>Thanks,</p>
