change in color handling (or bug in 0.90.1) ?

Community matplotlib-users

Hello -

This used to work:
fill( [0,1,1], [0,0,1], ‘#FFFF66’)

But it doesn’t work anymore under 0.90.1.
I thought it still worked under 0.90.0

Anybody see the same problem?
Plot seems to have the same problem:

plot([1,2,3],’#afeeee’)

Error message for the plot statement:
Traceback (most recent call last):
File “<pyshell#11>”, line 1, in ?
plot([1,2,3],’#afeeee’)
File “C:\Python24\Lib\site-packages\matplotlib\pylab.py”, line 2028, in plot

ret =  gca().plot(*args, **kwargs)

File “C:\Python24\Lib\site-packages\matplotlib\axes.py”, line 2535, in plot
for line in self._get_lines(*args, **kwargs):
File “C:\Python24\Lib\site-packages\matplotlib\axes.py”, line 421, in _grab_next_args

for seg in self._plot_2_args(remaining, **kwargs):

File “C:\Python24\Lib\site-packages\matplotlib\axes.py”, line 313, in _plot_2_args
linestyle, marker, color = _process_plot_format(fmt)
File “C:\Python24\Lib\site-packages\matplotlib\axes.py”, line 153, in _process_plot_format

raise ValueError, err

ValueError: Unrecognized character # in format string

Thanks, Mark

I don't think this behavior is documented, and a very quick look at recent changes to axes.py did not reveal a corresponding change, but it looks like it would be easy add and it seems to me like a useful and logical extension. The idea is that if a string is a valid mpl colorspec (including, but not limited to, hex strings as in the example above), then it sets the color; otherwise the present code is used to interpret strings like '-k' etc.

If no one is working on this, and if there is no objection, I can implement it later today or tomorrow. Does anyone see any ambiguity or other problem with this?

I know for a fact that it used to work for fill( [0,1,1], [0,0,1], ‘#FFFF66’).
But maybe I was just lucky.
It would be nice if you can make the change officially,
