Hello Teddy,

You have to disable anti-aliasing and jittering from the NChartControl.Settings object. You can also disable the surface frame lines if you don't need them. Lighting is not necessary for flat surfaces, so it can be disabled too. By the way, we are currently working on some performance improvements that should speed up rendering of surface charts.

The control does't support refresh of individual series. In general this is not possible for 3D charts, and for 2D charts we don't have such a feature at this point.

Hi,

I had a few questions regarding fast updating of NChartControl. I am working with a fairly large NGridSurfaceSeries data set (~200k points). I need to be able to refresh this chart with this series in it very quickly (if this helps I am using an enable3D=true and drawflat=true setup). Is there any way I can maximize the speed of the NChartControl.refresh() command? 

A follow up question is if I have an NChartControl with 2 series in it, is there a way to only refresh one of the series at a time? If this is not currently supported, does anybody know if this feature is in development?

Thank you very much!
