HI,  
I am looking to create a single topoplot, one each of Delta, Theta, Alpha  
and Beta frequency bands. How could I get these with an interactive time  
varying slider.

We need to see these frequency variations at any instant of time . How can  
we achieve this to pass time component as a parameter

So far have been able to plot with evoked.plot\_topomap() for the complete  
evoked array. However for now i need to restrict it to a particular time  
for all the frequency bands individually

Regards,  
Sundar.
