Class Description

*-*-*-*-*-*-*-*-*-*-*The H I S T O G R A M   Classes*-*-*-*-*-*-*-*-*-*-*-*
*-*                  ===============================
*-*
*-*  ROOT supports the following histogram types:
*-*
*-*   1-D histograms:
*-*      TH1C : histograms with one byte per channel.   Maximum bin content = 255
*-*      TH1S : histograms with one short per channel.  Maximum bin content = 65535
*-*      TH1F : histograms with one float per channel.  Maximum precision 7 digits
*-*      TH1D : histograms with one double per channel. Maximum precision 14 digits
*-*
*-*   2-D histograms:
*-*      TH2C : histograms with one byte per channel.   Maximum bin content = 255
*-*      TH2S : histograms with one short per channel.  Maximum bin content = 65535
*-*      TH2F : histograms with one float per channel.  Maximum precision 7 digits
*-*      TH2D : histograms with one double per channel. Maximum precision 14 digits
*-*
*-*   3-D histograms:
*-*      TH3C : histograms with one byte per channel.   Maximum bin content = 255
*-*      TH3S : histograms with one short per channel.  Maximum bin content = 65535
*-*      TH3F : histograms with one float per channel.  Maximum precision 7 digits
*-*      TH3D : histograms with one double per channel. Maximum precision 14 digits
*-*
*-*   Profile histograms: See class TProfile
*-*
*-*- All histogram classes are derived from the base class TH1

*-*   The TH*C classes also inherit from the array class TArrayC.
*-*   The TH*S classes also inherit from the array class TArrayS.
*-*   The TH*F classes also inherit from the array class TArrayF.
*-*   The TH*D classes also inherit from the array class TArrayD.
*-*
*-*   Convention for numbering bins
*-*   =============================
*-*   For all histogram types: nbins, xlow, xup
*-*     bin = 0;       underflow bin
*-*     bin = 1;       first bin with low-edge xlow INCLUDED
*-*     bin = nbins;   last bin with upper-edge xup EXCLUDED
*-*     bin = nbins+1; overflow bin
*-*
*-*  Associated errors
*-*  =================
*-*  By default, for each bin, the sum of weights is computed at fill time.
*-*  One can also call TH1::Sumw2 to force the storage and computation
*-*  of the sum of the square of weights per bin.
*-*  If Sumw2 has been called, the error per bin is computed as the
*-*  sqrt(sum of squares of weights), otherwise the error is set equal
*-*  to the sqrt(bin content).
*-*
*-*  Associated functions
*-*  ====================
*-*  One or more object (typically a TF1*) can be added to the list
*-*  of functions (fFunctions) associated to each histogram.
*-*  When TF1::Fit is invoked, the fitted function is added to this list.
*-*
