Re: [Matplotlib-users] Smooth animations

[v0idnull <v0i...@ps...>]

eh....

Let me explain my problem in a different way:

Every two seconds I get a value from a service. Let's say I over 8 
seconds I get 1, 5, 10, 5 as values.

So if my application updates the graph every two seconds, this will look 
choppy and ugly. This is because every two seconds, an entire line is 
added onto the graph between the two points.

Imagine if I could control the drawing of said line though. If I could 
draw the individual pixels of the line every couple of ticks instead of 
just dumping a line in every two seconds, I will end up with a nice 
smooth animation. It may not be 100% real time anymore, but my focus on 
this personal project of mine is vanity, not practicality ;)

I hope this better explains what I am trying to accomplish...

Thanks,
