Thanks for the full example, but if you carefully read the exception, it was
telling you the problem. :)  plot1 here is an axes object, which does not
have a colorbar() method.  Instead, you should change that to:

plt.colorbar()

Assuming everything else was working, you should be good to go with this
change.
