Hi there,

Caching certain things that are drawn as part of your chart (most notably the background grid) will increase the performance a large amount. The next version of RGraph will include a "drawing cache" that will be used to avoid repeated drawing of parts of the chart. This is most notable when using the Bar chart Wave effect.
