Hi everybody,
I have the problem, that I cannot add a color bar to a pcolor plot, which I
generate of some Data files. If I do
fig = plt.figure()
plot1 = fig.add_subplot(231,aspect='equal')
plot1.pcolor(xsr)
plot1.axis([0, 127, 0, 127])
plot1.colorbar()
it just gives me
AttributeError: 'AxesSubplot' object has no attribute 'colorbar'
WARNING: Failure executing file: <test.py>
What am I doing wrong? At the end of this file you find the whole plot-file
Thank you for your help,
Markus
