Hi Robert,

I assume that you mean "I am drawing a TH2D using the "SURF2Z" option"
not a TH3D.

In the CVS version, the logic to draw the color palette has been modified.
Like for the TPaveStats, there is now a new class TPaletteAxis added
to the histogram list of functions.
You can get a pointer to this object with:
TPaletteAxis *palette =
(TPaletteAxis*)h->GetListOfFunctions()->FindObject("palette");

Interactively with the mouse, you can move/resize the palette,
and also via the context menu change the axis attributes.
