Hi,

I have a set of data consisting on coordenates (X,Y,Z) and a value for each coordenate (1,1,1,0.5; 1,2,1,0.90; ...)
I need to represent in a chart a different color for each point depending on its value. I forget about the Z and use only the X and Y, as I manage to solve a different solution to show the values for a specific Z.

At the moment I am using a NChartControl with a serie of type NGridSurfaceSeries that I load with X, Y and value (surface.Data.SetValue(1, 1, 0.5))

The representation looks fine. However, now I need to show some specific points on the chart. These are not points that are in the serie that I represent. I also would need to implement functionality so the user can click somewhere on the chart (or pass over with the mouse) and the coordenates and value for the point is shown.

I cannot find the way to do this with this chart. Is it possible or should I change the type of chart (and if so, what chart or serie type should I use)?

Thanks,
