Indeed...and I wish the behavior was more like other mpl functions. Either way, passing my list through a colormap did not solve the issue (for me). If I call: scatter(x,y,s,c) then I get a scatter plot where the points are different sizes and colors. Without specifying the keyword 'edgecolor', it is not possible to have varying edge colors. For consistency, I set the facecolors through a keyword as well. So, I would like to be able to make the following command: scatter(x,y,s, facecolor=cm.jet(c), edgecolor=cm.jet(ec)) where, as noted, we must manually map the colors when specifying via keywords. However, when I run the above command, I do not get a scatter plot with varying sizes, colors, and edgecolors. Instead, I get varying sizes, all points with 'b' as a facecolor, and all points with 'k' as an edgecolor. I've tried to figure this out...comments are requested... I am looking at axes.py/scatter now.... When I make the above statement, c takes on its default value (which is 'b'). The function sees that c is string like and converts it to a rgba_list. Since 'faceted' defaults to True, edgecolors=None. Now we go through and create the *PolyCollection. For 'facecolors' we pass in 'b'...and for 'edgecolors' we pass in None. After creation, collection.update(kwargs) is called. As I understand it, this is what *should* happen when the update method is called: The collection should take my keywords 'facecolor' and 'edgecolor' and assign them to self._facecolors and self._edgecolors. This does occur (as my first reply demonstrated). It seems what should *also* happen is that the facecolors/edgecolors of the points should be updated...but this does not occur. Do you (or does anybody) have a working, simple example where the faces/edges are both varying for a scatter plot? Perhaps I've missed something obvious. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
