Returning Coordinate Values
The ChartGroups collection provides methods which enable you to do the following:
· Determine the pixel coordinates of a given data point, or the closest point to a given set of pixel coordinates.
· Convert from data coordinates to screen pixel coordinates and vice versa.
· Change the Z-value of a grid location.
· Determine the Z-value of any point on the surface.
