Thanks for the full example, but if you carefully read the exception, it

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.
It looks like Markus is trying to use the API, so rather than suggest
the pyplot colorbar method, I suggest using the figure instance
method. Markus the pyplot method plt.colorbar is a thin wrapper
around the figure method fig.colorbar -- see also:
http://matplotlib.sourceforge.net/faq/usage_faq.html#matplotlib-pylab-and-pyplot-how-are-they-related
http://matplotlib.sourceforge.net/api/figure_api.html#matplotlib.figure.Figure.colorbar
It may be a good idea and refer to the return value of fig.add_subplot
as ax or something that, rather than plot1 because add_subplot
returns an Axes instance and thus ax is a better mnemonic; see
http://matplotlib.sourceforge.net/api/figure_api.html#matplotlib.figure.Figure.add_subplot
So I suggest something like::
fig = plt.figure()
ax1 = fig.add_subplot(231,aspect='equal')
ax1.pcolor(xsr)
ax1.axis([0, 127, 0, 127])
fig.colorbar()
Except that it won't work like that. :) (I actually tried that the first
time) You need to give Figure.colorbar() the mappable as the first
argument. So this would then become:
ax1 = fig.add_subplot(231,aspect='equal')
pc = ax1.pcolor(xsr)
ax1.axis([0, 127, 0, 127])
fig.colorbar(pc)
