Profile2D histograms are used to display the mean value of Z and its RMS for each cell in X,Y.
Profile2D histograms are in many cases an elegant replacement of three-dimensional histograms : the inter-relation of three measured quantities X, Y and Z can always be visualized by a three-dimensional histogram or scatter-plot; its representation on the line-printer is not particularly satisfactory, except for sparse data. If Z is an unknown (but single-valued) approximate function of X,Y this function is displayed by a profile2D histogram with much better precision than by a scatter-plot.
The following formulae show the cumulated contents (capital letters) and the values displayed by the printing or plotting routines (small letters) of the elements for cell I, J.
H(I,J) = sum Z E(I,J) = sum Z l(I,J) = sum l L(I,J) = sum l h(I,J) = H(I,J)/L(I,J) s(I,J) = sqrt(E(I,J)/L(I,J)- h(I,J)**2) e(I,J) = s(I,J)/sqrt(L(I,J))
In the special case where s(I,J) is zero (eg, case of 1 entry only in one cell) the bin error e(I,J) is computed from the average of the s(I,J) for all cells if the static function TProfile2D::Approximate has been called. This simple/crude approximation was suggested in order to keep the cell during a fit operation. But note that this approximation is not the default behaviour.

Normal Constructor for Profile histograms.
The first eight parameters are similar to TH2D::TH2D. All values of z are accepted at filling time. To fill a profile2D histogram, one must use TProfile2D::Fill function.
Note that when filling the profile histogram the function Fill checks if the variable z is between fZmin and fZmax. If a minimum or maximum value is set for the Z scale before filling, then all values below zmin or above zmax will be discarded. Setting the minimum or maximum value for the Z scale before filling has the same effect as calling the special TProfile2D constructor below where zmin and zmax are specified.
H(I,J) is printed as the cell contents. The errors computed are s(I,J) if CHOPT='S' (spread option), or e(I,J) if CHOPT=' ' (error on mean).
See TProfile2D::BuildOptions for explanation of parameters

Reimplemented from TH2.
Definition at line 1289 of file TProfile2D.cxx.
Profile histogram is resized along axis such that x is in the axis range.
The new axis limits are recomputed by doubling iteratively the current axis range until the specified value x is within the limits. The algorithm makes a copy of the histogram, then loops on all bins of the old histogram to fill the extended histogram. Takes into account errors (Sumw2) if any. The axis must be extendable before invoking this function.
Ex: h->GetXaxis()->SetCanExtend(kTRUE)

Return bin effective entries for a weighted filled Profile histogram.
In case of an unweighted profile, it is equivalent to the number of entries per bin The effective entries is defined as the square of the sum of the weights divided by the sum of the weights square. TProfile::Sumw2() must be called before filling the profile with weights. Only by calling this method the sum of the square of the weights per bin is stored.

This function computes the min/max for the axes, compute a new number of bins, if necessary, add bin contents, errors and statistics. If overflows are present and limits are different the function will fail. The function returns the total number of entries in the result histogram if the merge is successful, -1 otherwise.
IMPORTANT remark. The 2 axis x and y may have different number of bins and different limits, BUT the largest bin width must be a multiple of the smallest bin width and the upper limit must also be a multiple of the bin width.

Rebin this histogram grouping nxgroup/nygroup bins along the xaxis/yaxis together.
if newname is not blank a new profile hnew is created. else the current histogram is modified (default) The parameter nxgroup/nygroup indicate how many bins along the xaxis/yaxis of this have to be merged into one bin of hnew If the original profile has errors stored (via Sumw2), the resulting profile has new errors correctly calculated.
examples: if hpxpy is an existing TProfile2D profile with 40 x 40 bins
NOTE : If nxgroup/nygroup is not an exact divider of the number of bins, along the xaxis/yaxis the top limit(s) of the rebinned profile is changed to the upper edge of the xbin=newxbins*nxgroup resp. ybin=newybins*nygroup and the remaining bins are added to the overflow bin. Statistics will be recomputed from the new bin contents.

Redefine x, y and z axis parameters.
The X, Y and Z axis parameters are modified. The bins content array is resized if errors (Sumw2) the errors array is resized The previous bin contents are lost To change only the axis limits, see TAxis::SetRange

Redefine x, y and z axis parameters with variable bin sizes.
The X, Y and Z axis parameters are modified. The bins content array is resized if errors (Sumw2) the errors array is resized The previous bin contents are lost To change only the axis limits, see TAxis::SetRange xBins is supposed to be of length nx+1, yBins is supposed to be of length ny+1, zBins is supposed to be of length nz+1

Set option to compute profile2D errors.
The computation of the bin errors is based on the parameter option:
See TProfile::BuildOptions for a detailed explanation of all options

Create/Delete structure to store sum of squares of weights per bin.
This is needed to compute the correct statistical quantities of a profile filled with weights
This function is automatically called when the histogram is created if the static function TH1::SetDefaultSumw2 has been called before. If flag is false the structure is deleted
