Stephen, This worked almost perfectly, except that the 'fill' feature seems to be broken. No matter how I set it, it always plots a filled in circle. Is there some way to get around this? Thanks, Brian On Sep 18, 2010, at 11:09 PM, Stephen Skory wrote:

Hi Brian,

Hello everyone, could someone tell me how to plot a sphere in a color other than

black? I've got this much working: p.modify['sphere']((x,y,z), radius, ) to plot a sphere at x, y, z of radius radius, but I cannot seem to succeed in changing the color.

It's not obvious how to do this. You need to make a dict with the properties of the circle you want, taken from here:

Brian, This rings a few bells for me -- which version of Matplotlib are you using? python2.6 -c "import matplotlib; print matplotlib.__version__" should get the info. -Matt On Wed, Sep 22, 2010 at 12:46 PM, Stephen Skory <stephenskory@yahoo.com> wrote:

I am unable to reproduce this bug. The "fill" is being respected in my tests. Can you share the script that you've tried?
