ExtJS 4 charts performance
The performance of the charts in ExtJS 4.0 seems to be very low. For instance, in line charts there is a significant delay in drawing the points and animation even for 100 points or less.
I have seen mobile charting frameworks that are more responsive for such a reduced number of points.
Also, desktop charting packages become that unresponsive at 10000+ points.
