Use the ZoneMethod Contour property to specify how to determine each zone region. Contour zoning uses the contour intervals for each zone region, while cell zoning uses the rectangular block formed by the X/Y grid. Cell zoning produces a coarser-looking surface but redraws significantly faster than contour zoning. ZoneMethod is located on the General Tab (ChartGroup) on the Property Pages.
