This turns on highlighting of chart elements by rendering a slightly smaller version of an identical chart element on top of the existing chart element. If the underlying chart element has texturing or shading that should show through, then consider setting the HighlightFillColor to a partially transparent color (one with an alpha component of less than 255).
Highlighting added by this method can be removed by just calling SetHighlightClearAll. If the supplied row and column is not valid (or it does not correspond to a chart element being displayed) then no chart element will be highlighted.
