In this way I cut all the values below 0.01. I want both positive and negative values but the point is that bin with value 0 shouldn't be painted, that is what happens when I only have positive value (or if I set a minimum like you suggest).

I'm thinking about cloning the TGAxis of the TPaletteAxis of the histogram, adding h->GetMinimum() to the filled values and painting the new histogram with the new palette but with the old palette axis. I wasn't able to do it and maybe there's a better and shorter solution.
