Class Description

*-*  The 3-D histogram classes derived from the 1-D histogram classes.
*-*  all operations are supported (fill, fit).
*-*  Drawing is currently restricted to one single option.
*-*  A cloud of points is drawn. The number of points is proportional to
*-*  cell content.

  TH3C a 3-D histogram with one byte per cell (char)
  TH3S a 3-D histogram with two bytes per cell (short integer)
  TH3F a 3-D histogram with four bytes per cell (float)
  TH3D a 3-D histogram with eight bytes per cell (double)


TH3C(): TH1C(),TH3()


TH3C(const char *name,const char *title,Int_t nbinsx,Axis_t xlow,Axis_t xup ,Int_t nbinsy,Axis_t ylow,Axis_t yup ,Int_t nbinsz,Axis_t zlow,Axis_t zup) :TH1C(3,name,title,nbinsx,xlow,xup), TH3()
*-*-*-*-*-*-*-*-*Normal constructor for fix bin size 3-D histograms*-*-*-*-*
*-*              ==================================================

TH3C(const char *name,const char *title,Int_t nbinsx,Axis_t *xbins ,Int_t nbinsy,Axis_t *ybins ,Int_t nbinsz,Axis_t *zbins) :TH1C(3,name,title,nbinsx,xbins), TH3()
*-*-*-*-*-*-*-*Normal constructor for variable bin size 3-D histograms*-*-*-*
*-*            =======================================================

TH3C(const TH3C &h3c)

void Copy(TObject &newth3)
*-*-*-*-*-*-*Copy this 3-D histogram structure to newth3*-*-*-*-*-*-*-*-*-*
*-*          ===========================================

TH1* DrawCopy(Option_t *option)

Int_t Fill3(Axis_t x, Axis_t y, Axis_t z, Stat_t w)
*-*-*-*-*-*-*-*-*-*-*Increment cell defined by x,y,z by a weight w*-*-*-*-*
*-*                  =============================================
*-* If the storage of the sum of squares of weights has been triggered,
*-* via the function Sumw2, then the sum of the squares of weights is incremented
*-* by w^2 in the cell corresponding to x,y,z.

void Reset(Option_t *option)
*-*-*-*-*-*-*-*Reset this histogram: contents, errors, etc*-*-*-*-*-*-*-*
*-*            ===========================================
