[Matplotlib-users] change in color handling (or bug in 0.90.1) ?

[Mark B. <ma...@gm...>]

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,
