Hi, I have a similar problem to the one described here: https://root-forum.cern.ch/t/2d-histograms-with-col-option/18603/6
My TH2F histogram has values close to 0 in it, but they are being drawn white instead of the lowest color on the palette:
I.e. the white 0.009 value should be blue. I have tried the “colz0”, “colz” and “colz1” options (in ROOT 6), but they all produce the same results. I would set the background color to be the lowest value, but I actually want the white space below the diagonal cells to represent no entries. Are these options not the right ones for this problem? Thank you.
