Code for reproduction
from pylab import *
imshow(np.random.rand(100, 100), norm=mpl.colors.LogNorm())
colorbar(boundaries=[1e-4, 1e-3, 1e-2, 1])Actual outcome
Expected outcome
Either properly positioned boundaries, or (better) disallow passing boundaries in such cases.
Note that the docstrings in colorbar.py say
The following will probably be useful only in the context of
indexed colors (that is, when the mappable has norm=NoNorm()),
or other unusual circumstances.
============ ===================================================
Property Description
============ ===================================================
*boundaries* None or a sequence
*values* None or a sequence which must be of length 1 less
than the sequence of *boundaries*. For each region
delimited by adjacent entries in *boundaries*, the
color mapped to the corresponding value in values
will be used.
============ ===================================================
but that still ends up part of the public API, which makes my intended fix for #7320 more difficult...
