Re: [Matplotlib-users] question about animation and widgets

[bruno <bru...@ia...>]

Hi thanks for the answer. I am not sure to undersand completely the 
question. I based my animation on the example anim.py using the ion() 
function. Is that idle event ?

I will have a look at the wx version an see if I undersand your advice.

If ever you had code that you were willing to share I would be very 
thankfull.

Already many thanks

Bruno
