PercentilePivots 

The function PercentilePivots returns the z value at the percentile prob of all pivot points. The valid range of prob is 0 to 100. The function comes in two overloaded variants. Version [2] allows to exclude all pivot points which are covered by the Mask array from the calculation of the percentile. This way you may restrict the calculation of the percentile to unmasked regions only. PercentilePivots should be called only after recalculating the pivot points (CalculatePivotPoints) or after a complete redraw of the contour plot (i.e. after calling the method DrawPlot), otherwise the results may be wrong.
