I don't quite understand: what kind of "c" are you passing in, what is
the original code doing with it, and what should it do with it? (I find
both the original and the suggested code hard to understand, which makes
me think that neither is actually what we want.)
c is a named argument of the scatter method for the colors, but it is
modified to get the real "colors" argument.
I think that what we want may be the following:
try:
colors = colorConverter.to_rgba_list(c, alpha)
except TypeError:
colors = None # generate colors later by applying a colormap to c
Part of what makes all this hard to understand is that in the None case,
colors are generated from c far down in the code, out of sight of this
initial processing. Hence the comment.
OK, now I see that what I proposed won't work until I rip out the
long-deprecated float-as-grey option. Looks like a good time for me to
do it.
