3.14.2 ContXYZ

These plotting functions draw contour lines in x, y, or z plain. If a is a tensor (3-dimensional data) then interpolation to a given sVal is performed. These functions are useful for creating projections of the 3D data array to the bounding box. For example, code like

gr->ContX(c.Sum("x"),"BbcyrR",-1);
gr->ContY(c.Sum("y"),0,1);
gr->ContZ(c.Sum("z"),0,-1);

will produce the following picture. See also ContFXYZ, DensXYZ, Cont, Data distributions. See section Cont projection sample, for sample code and picture.
