I guess, it shall be the center values of the values displayed, but then the implementation for this in ColorbarBase._process_values() would be broken. The ColorbarBase simply makes a strip of colored blocks, with their sizes and locations determined by the boundaries kwarg (together with the spacing kwarg) and their colors determined from the values kwarg via color mapping. If either or both of these kwargs is None, the boundaries and/or values will be generated in _process_values. The use of the non-default values kwarg is illustrated by the special-case handling of colorbars for contouring in the Colorbar class. Can you give a test case showing a problem with _process_values? Friedrich P.S.: I assume you have be caught by the misconfiguration of the list that the sender is used as the default recipient, so I post back to the list? The mpl lists have been unusual (at least compared to lists for numpy, scipy, and cython) in this respect for years. Usually I remember to reply to all, but you are right--this time I goofed.

[Matplotlib-users] colorbar.Colorbar ticking
I noticed that colorbar.Colorbar treats segmentation via *boundaries* as compulsory, i.e., it thinks it must tick at the *boundaries* or nowhere. Wouldn't it be useful to have an kwarg which overrides this and always uses ticker.MaxNLocator()? Friedrich -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.
