Hello Nevron,

I'm attempting to graph various sets of 3D data using the NGridSurfaceSeries. Following the example from NGridSurfaceUC.cs, I can display an initial set of data, but if I attempt to change the values of that series later, the display doesn't update. I've checked the data for the series after the change, and it does contain the new data, but the display doesn't reflect the change.

I've also tried deleting the initial surface, then adding it back. I also tried not creating an inital surface, and creating the first surface from the button click.

Can you tell me what I may be doing wrong?

Thanks, Brian Warren

Hi Brian,

Just call

nChartControl1.Refresh();

instead of

nChartControl1.Update();

Hi Milen,

Of course. Thank you!

Best regards, Brian
