Draw a 2D with 3rd variable filling the "colz"

Hello

I am trying to find how it is possible to modify starting from something like

tree->Draw("a:b:c")

so to actually get a 2D (a:b) with “c” filling the “colz”. Is this possible ?

thanks

Alex

I’m not sure what you really want, so try (note: you should have “c” >=0):
tree->Draw(“a:b:c”, “”, “colz”)
tree->Draw(“a:b”, “c”, “colz”)
