A couple of things I would like to point out here:
1.) It is possible that Debashish sent similar questions to multiple
mailing lists in the hopes to maximize the chance of getting a response.
It may only "appear" that this thread was started after having the question
answered on another mailing list because of the delays that are notorious
on this list. I suspect he sent both emails at around the same time, but
the python tutors list processed it faster than the matplotlib-users list.
Therefore...
2.) I would like to make sure that this mailing list remains a welcoming
forum for all users, and for all of us to understand that people have
different mailing habits that we may not be familiar with. Therefore,
gentle reminders of mailing decorum (such as reminders to bottom-post)
should be the response, not chastising.
-- Debashish,
We are more than happy to help you. Please keep your question to a single
mailing list at a time. The users on the mailing list will let you know if
you should direct your question elsewhere. In the case of your problem, it
is not matplotlib, but mayavi. Hopefully, you have been directed to the
mayavi mailing list.
Cheers!

Didn't this get answered on the python tutor mailing list within the
last couple of hours? What's with it with you?
