Create an empty histogram that can be filled with the addBin() and addAsymmetryBin() methods.
Use the optional parameter to specify the confidence level in units of sigma to use for calculating error bars. The nominal bin width specifies the default used by addBin(), and is used to set the relative normalization of bins with different widths.

Create a histogram from the contents of the specified TH1 object which may have fixed or variable bin widths.

Use the optional parameter to specify the confidence level in units of sigma to use for calculating error bars. The nominal bin width specifies the default used by addBin(), and is used to set the relative normalization of bins with different widths.

Create a histogram from the asymmetry between the specified TH1 objects which may have fixed or variable bin widths, but which must both have the same binning.
The asymmetry is calculated as (1-2)/(1+2). Error bars are calculated using Binomial statistics. Prints a warning and rounds any bins with non-integer contents. Use the optional parameter to specify the confidence level in units of sigma to use for calculating error bars. The nominal bin width specifies the default used by addAsymmetryBin(), and is used to set the relative normalization of bins with different widths.

Create histogram as sum of two existing histograms.
If Poisson errors are selected the histograms are added and Poisson confidence intervals are calculated for the summed content. If wgt1 and wgt2 are not 1 in this mode, a warning message is printed. If SumW2 errors are selectd the histograms are added and the histograms errors are added in quadrature, taking the weights into account.
