Contour / Surface with undefined data

[aansnmoran]

Hi

I have to display Contout/Surface chart with some undefined data
(number of points in data grid are not defined) for example limited number of points for surface defintion

The problem is that contour/surface chart hides the data around the undefined points and in case of limited and random points TeeChart does not display the surface at all.

Regards,
Arie

Hi Arie,

Please notice that ColorGrid and Surface series need to have "matrix" structure, X and Z values defining the rows and columns and Y values determining cells value. It should be able to be populated using a nested for loop as shown below. If you don't want some cells not being visible you can set it to Color.Transparent as shown in the example.

Code: Select all

			for (int x=0; x<10; ++x)
				for (int z=0; z<10; ++z)
					if (x % 2 == 0)
						surface1.Add(x,x*z,z,Color.Transparent);
					else
						surface1.Add(x,x*z,z);

If X and Z values are not equidistant then you should use:

Code: Select all

			surface1.IrregularGrid=true;
