Hi,

I have a chart with two series. One is a 150k point NGridSurface series and the other is a 2 point NLineSeries. I just want to be able to refresh the 2 point NLineSeries, not the NGridSurface series since this takes too much time. Is there a way to only update one series and not the entire NChart?

Thank you,

Teddy

Hi Teddy,

Currently there is no way to update only specific parts of a scene. This is possible to some extent with 2D charts, where some elements can be painted in "overlay". However in 3D charts the whole scene is always repainted.

Sorry, I was not specific enough in my original question. The NGridSurfaceSeries is actually a top-down view of the surface I am plotting. Essentially the viewer sees it as "flat."

Is there a method of plotting top-down views in Nevron Chart that do not use an NGridSurface or any 3D plotting?

Regards,

Teddy

Hi Teddy,

The control can display surface / countour charts only in 3D mode even if they are displayed in 2D projection. A possible solution is to use an "off-screen" chart to pre-generate a texture that displays only the countour chart without axes, labels, etc. and then map this texture on a mesh surface that has just several data points. This will be much faster to render, but you'll have to take care to re-generate the contour texture when necessary.
