I really like this lib, it produces very lovely graphs with very little effort.

I'm trying to use it to create live graphs, which update in real-time (every second) and I'm seeing big spikes in memory and GPU usage. Could you give me any suggestions on how I could streamline the library to speed up this performance? I've dropped alpha to zero and turned off beziers - scratching the surface to be sure - are there any other low hanging fruit that I could tackle?
thanks again
Jason
