void THnBase::Multiply | ( | const THnBase * | h | ) |
Multiply this histogram by histogram h this = this * h Note that if h has Sumw2 set, Sumw2 is automatically called for this if not already set.
Definition at line 909 of file THnBase.cxx.
Performs the operation: this = this*c*f1 if errors are defined, errors are also recalculated.
Only bins inside the function range are recomputed. IMPORTANT NOTE: If you intend to use the errors of this histogram later you should call Sumw2 before making this operation. This is particularly important if you fit the histogram after calling Multiply()

Print a THnBase.
If "option" contains:
Reimplemented from TObject.

Print one bin.
If "idx" is != -1 use that to determine the bin, otherwise (if "idx" == -1) use the coordinate in "bin". If "options" contains:

Print bin with linex index "idx".
For valid options see PrintBin(Long64_t idx, Int_t* bin, Option_t* options).

Project all bins into a 3-dimensional histogram, keeping only axes "xDim", "yDim", and "zDim".
If "option" contains:
Project all bins into a 1-dimensional histogram, keeping only axis "xDim".
If "option" contains:
Project all bins into a 2-dimensional histogram, keeping only axes "xDim" and "yDim".
WARNING: just like TH3::Project3D("yx") and TTree::Draw("y:x"), Projection(y,x) uses the first argument to define the y-axis and the second for the x-axis!
If "option" contains "E" errors will be calculated. "A" ranges of the taget axes will be ignored.

Project all bins into a ndim-dimensional THn / THnSparse (whatever *this is) or if (ndim < 4 and !wantNDim) a TH1/2/3 histogram, keeping only axes in dim (specifying ndim dimensions).
If "option" contains:

Combine the content of "group" neighboring bins for each dimension into a new bin and return the resulting THnBase.
For group={2,1,1} and a 3 dimensional histogram, pairs of x-bins will be grouped.
Definition at line 1225 of file THnBase.cxx.
Combine the content of "group" neighboring bins into a new bin and return the resulting THnBase.
For group=2 and a 3 dimensional histogram, all "blocks" of 2*2*2 bins will be put into a bin.
Definition at line 1209 of file THnBase.cxx.
Add contents of h scaled by c to this histogram: this = this + c * h Note that if h has Sumw2 set, Sumw2 is automatically called for this if not already set.
In contrast to Add(), RebinnedAdd() does not require consistent binning of this and h; instead, each bin's center is used to determine the target bin.

Change (i.e.
set) the title.
If title is in the form "stringt;string0;string1;string2 ..." the histogram title is set to stringt, the title of axis0 to string0, of axis1 to string1, of axis2 to string2, etc, just like it is done for TH1/TH2/TH3. To insert the character ";" in one of the titles, one should use "#;" or "#semicolon".
