Thank you,                  I did contact them, but it appears he did not understand, the issue I was telling him. Then I thought it is my lack of expertise which made it not work.Sudheer

This would seem like a bug in that package's code. The traceback shows that it is performing its own check on the passed in kwargs, and failing to recognize it as a valid argument. I suggest contacting the maintainers of the "skill_metrics" package and find out from them if there is a bug in their package. I am unfamiliar with this package, so I can't say anything for certain.

Cheers!

Dear Experts.I have been trying to modify plot properties of taylor diagram from below package.

If I try to use markerfacecolor option the code says it do not know about such option. I was also checking it is possible specify alpha= n so that the color intensity of symbol can be modified.

Please advice if it is possible.Sudheer

I am wondering if the "optimizations" you have are actually slowing you
down. I have never found myself needing to flush_events() or call update()
like that. Or to draw the artists like you are doing. Without seeing more
of the code, it is hard to judge. Have you tried using "runsnakerun" to
profile your code to find out what is actually slowing it down? I can get
60-70Hz without even trying for 3d plotting animations, and that is
probably more computation than this.

Thanks for the help (and sorry for the super-late reply).

I just tried blitting, but it doesn't really help. I cannot exceed 20 fps.
The problem is that I'm plotting data from a video file, so that for each
frame I need to draw a new array (not just a foreground). I think its just
to much data.

Thanks,
Hjalmar
