RE: Changing size of the color palette and its scale

Hi,  

To change the palette you should use gStyle->SetPalette(...). For instance gStyle-->Palette(1) define a rainbow palette.  

If you want to change the "geometry" of the palette, you can do it interactively using the mouse.
Saving the modified pad as a .C file will show you which attributes you can change.  

To access the palette within a macro you should do: h->Draw("surf2z");
gPad->Update()
TPaletteAxis *p=
(TPaletteAxis*)h->GetListOfFunctions()->FindObject("palette");

Subject: [ROOT] Changing size of the color palette and its scale

Hi,

I have plotted a 2D matrix with the option h->Draw("SURF2Z");
and wonder how I can change the size of the drawn color palette, and also the numbers showing its scale?

Thanks in advance for your help!

Cheers, Cecilie
