This class creates a linear binning. For this the user must provide

• A minimum
• A maximum
• The number of bins

The information can be set either in the constructor

TLinearBinning mybinning(100, -10., 10.);

or using the set function

TLinearBinning mybinning;
mybinning.Set(100, -10, 10);

The binning can be converted to a TArrayD which contains the bin edges in increasing order:

TArrayD binlimits;
mybinning.CreateBinEdges(binlimits);

Note

In case the binning is used together with the THistManager the last step is done by the THistManager and does not need to be performed by the user.
