Description</sup>

^{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.}

^{Run this method when using the FastBrush Surface Series paint technique.}

^Example

^{With TChart1}

^{.Aspect.Orthogonal = False}

^{.Aspect.Zoom = 70}

^{.Series(0).FillSampleValues (30)}

^{' Speed trick, as we know Surface data will not be modified anymore:}

^{.Series(0).asSurface.FillGridIndex 0}

^{.Series(0).asSurface.ReuseGridIndex = True}

^{.Series(0).asSurface.Pen.Visible = False}

^{.Series(0).asSurface.FastBrush = True}

^{' other setting to increase speed:}

^{.ClipPoints = False}

^{.Walls.Left.Visible = False}

^{.Axis.FastCalc = True ' <-- bypass overflow checkings...}

^{End With}
