Hi,
I am creating a surface plot.  The coloring will be based on the surface value (Nevron y axis value).  I have implemented this by assigning the appropriate color to each vertex.  By using NGridSurfaceSeries.Data.Colors.  I used this method because I found an example in the documentation.  I then stumbled across the concept of a palette.  The documentation seems to hint I can create a custom palette to do the same thing.

1) Are there any advantages/disadvantages to assigning a color to each vertex vs using a custom palette?
2) Are there any examples for using a custom palette?  Perhaps even creating it from a known look up table?
Thanks

Hi Karl,

The preferred method in this case is to use a palette in ZoneTextureMode (in as this will decrease the amount of data transfer to the video board):
surface.FillMode = SurfaceFillMode.ZoneTexture;

Regarding the palette - the following code shows how to create a custom palette:

   surface.FillMode = SurfaceFillMode.ZoneTexture;
   surface.Palette.Clear();
   surface.Palette.Mode = PaletteMode.Custom;

   surface.Palette.Add(0, Color.Red);
   surface.Palette.Add(0.20, Color.Blue);
   surface.Palette.Add(0.40, Color.Green);
   surface.Palette.Add(1, Color.Yellow);

in this palette values that fall in the range [0, 0.2] will be colored red, [0.2, 0.4] Blue and so on.

Hope this helps - let us know if you have any questions.
