I was wondering if there exists a way to leave empty bins white when drawing an TH2F with the"lego2 z pol" option.
Some of my fills are close to zero, so I can’t know anymore which bins are empty and which ones have just a small value…
This option doesn’t exist. It is that way with COLZ but not with LEGO plots Have you tried to define your own palette with color white on low level bins ? I guess making it with a lot of colors and redefining the low level indices to white should make it.
