I think you are looking for the Figure.colorbar() method if you are using the OO API. If you are using the pylab interface, it is pylab.colorbar: > colorbar() > > , line 499, in <module> > colorbar() > File "C:\Python25\Lib\site-packages\matplotlib\pyplot.py", line 1129, in > colorbar > ret = gcf().colorbar(mappable, cax = cax, ax=ax, **kw) > File "C:\Python25\Lib\site-packages\matplotlib\figure.py", line 956, in > colorbar > cb = cbar.Colorbar(cax, mappable, **kw) > File "C:\Python25\Lib\site-packages\matplotlib\colorbar.py", line 558, in > __init__ > mappable.autoscale_None() # Ensure mappable.norm.vmin, vmax > AttributeError: 'NoneType' object has no attribute 'autoscale_None' > > I am not sure how the mappable, ax, and cax options work.
