Truncate one sharp peak for 2D histogram

[Liuyao_Zhang]

Dear experts,

Could you share how the peak (Deta~0, Dphi~0) is truncated for one 2D histogram? Just like the picture I showed. Actually, I tried to set the range at the z-axis, seemly it doesn’t work;

Best regards
Liuyao.

Set the maximum to something high h->SetMaximum(..) if it is still truncated it means your histogram has been filled like that. If not adjust the maximum to a reasonable value.

Thanks for your prompt reply;
