WebTo fit a histogram you can use the Fit Panel on a visible histogram via the context menu, or you can use the TH1 ::Fit method. The Fit Panel, which is limited, is best for prototyping. The histogram needs to be drawn in a pad before the Fit Panel is invoked. The method TH1::Fit is more powerful and is used in scripts and programs.
