Unit

Description
Internal use.
This method is called by the Series to create an internal grid template upon which to base the Surface or Contour plots.
If you pass exact grid X and Z values to the Series (ie, correlative integer numbers starting from zero), the FillGridIndex method will do nothing.
If the X and Z values are floating point, or they aren't ordered, the FillGridIndex method will construct a grid and sort the X and Z coordinates.
The resulting grid will be then used as an index for every point to display.
If you have XYZ values that cannot be fitted on a square grid, you can use the TriSurface Series.
