See the description of TH1 header and TH1::SetContour // Setting Drawing histogram contour levels (2-D hists only) // ========================================================= // By default contours are automatically generated at equidistant // intervals. A default value of 20 levels is used. This can be modified // via TH1::SetContour() or TH1::SetContourLevel(). // the contours level info is used by the drawing options "cont", "surf", // and "lego".
