remove useless semicolons
State: closed

Some semicolons were used without reason.

I don't think this is without reason? 
I think it supresses the output like `Out[15]: <matplotlib.axes._subplots.AxesSubplot at 0x7fc57ae70c50>` 

Still, question is if this is needed, but IMO it makes the docs a bit cleaner.
BTW, something that may not be needed is actually the full `plt.figure();`, but it should be checked that it works for plotting series without that (as series.plot(..) tends to plot an the existing previous figure in an interactive environment).
The semicolons that I remove were probably copy/paste mistakes
omg, it's seem to be a feature... there are some hidden tricks with IPython using semicolons.
