title: Is there a matplotlib counterpart of Matlab "stem3"?
body: <p>It is quite easy to make a 3d stem plot with stem3 command as documented in <a href="http://www.mathworks.com/help/techdoc/ref/stem3.html" rel="noreferrer">http://www.mathworks.com/help/techdoc/ref/stem3.html</a>
  I wonder if there is a similar command in matplotlib? I checked the online document for the latest version, but could not find one. Can anyone give some suggestions?</p>
