I see -- you want to basically interpolate between points?  I don't 
think there's anything built in to matplotlib to do that, but you could 
always do that interpolation outside and just update the graph more often.

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,

It looks like the version of Numpy installed on your machine is too old 
for the latest version of matplotlib.  You'll need at least version 1.5, 
I believe (though we neglected to update the documentation about this 
requirement).

Have you looked at the simple_anim.py example -- other than the 
networking piece, it seems to do what you describe, and it's pretty 
fast.  Maybe start from that and make changes until it gets slow in 
order to determine where the slowness comes from...?

I am receiving a number from a server every two seconds. I would like to plot this number.out over time for the past say... 30 polls.

Would it be possible to use... Anything, to produce a smooth animation of the plot line getting drawn? As it stands now the animation is well... Quite choppy. ;)

I'm using pygame currently to render my graphs on this full screen application I'm making just for my self. I am not bound to it though if there are better linux-only things out there.

Thanks in advance,
