Profile2D histograms are used to display the mean value of Z and its error 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.
\[ \begin{align} H(i,j) &= \sum w \cdot Z \\ E(i,j) &= \sum w \cdot Z^2 \\ W(i,j) &= \sum w \\ h(i,j) &= \frac{H(i,j)}{W(i,j)} \\ s(i,j) &= \sqrt{E(i,j)/W(i,j)- h(i,j)^2} \\ e(i,j) &= \frac{s(i,j)}{\sqrt{W(i,j)}} \end{align} \]
The bin content is always the mean of the Z values, but errors change depending on options:
\[ \begin{align} \text{GetBinContent}(i,j) &= h(i,j) \\ \text{GetBinError}(i,j) &= \begin{cases} e(i,j) &\text{if option="" (default). Error of the mean of all z values.} \\ s(i,j) &\text{if option="s". Standard deviation of z values.} \\ \begin{cases} e(j) &\text{if } h(i,j) \ne 0 \\ 1/\sqrt{12 N} &\text{if } h(i,j)=0 \end{cases} &\text{if option="i". This is useful for storing integers such as ADC counts.} \\ 1/\sqrt{W(i,j)} &\text{if option="g". Error of a weighted mean when combining measurements with variances of } w. \\ \end{cases} \end{align} \]
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
see other constructors below with all possible combinations of fix and variable bin size like in TH2D.

Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.
In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Check and record whether this class has a consistent Hash/RecursiveRemove setup (*) and then return the regular Hash value for this object.
The intent is for this routine to be called instead of directly calling the function Hash during "insert" operations. See TObject::HasInconsistenTObjectHash();
(*) The setup is consistent when all classes in the class hierarchy that overload TObject::Hash do call ROOT::CallRecursiveRemoveIfNeeded in their destructor. i.e. it is safe to call the Hash virtual function during the RecursiveRemove operation.

In case several cells in the specified range satisfy diff <=maxdiff the cell with the smallest difference is returned in binx,biny. In all cases the function returns the smallest difference.
NOTE1: if firstxbin < 0, firstxbin is set to 1 if (lastxbin < firstxbin then lastxbin is set to the number of bins in X ie if firstxbin=1 and lastxbin=0 (default) the search is on all bins in X except for X's under- and overflow bins. if firstybin < 0, firstybin is set to 1 if (lastybin < firstybin then lastybin is set to the number of bins in Y ie if firstybin=1 and lastybin=0 (default) the search is on all bins in Y except for Y's under- and overflow bins.
NOTE2: if maxdiff=0 (default), the first cell with content=c is returned.

The returned function value is the probability of test (much less than one means NOT compatible)
The KS test uses the distance between the pseudo-CDF's obtained from the histogram. Since in 2D the order for generating the pseudo-CDF is arbitrary, two pairs of pseudo-CDF are used, one starting from the x axis the other from the y axis and the maximum distance is the average of the two maximum distances obtained.

Project a 2-D histogram into a 1-D histogram along X (integration along Y).
The projection is always of the type TH1D. The projection is made from summing the channels along the Y axis ranging from firstybin to lastybin included. By default, all bins including under- and overflow are included. The number of entries in the projection is estimated from the number of effective entries for all the cells included in the projection.
To exclude the underflow bins in Y, use firstybin=1. To exclude the overflow bins in Y, use lastybin=nx.
if option "e" is specified, the errors are computed. if option "d" is specified, the projection is drawn in the current pad. if option "o" original axis range of the target axes will be kept, but only bins inside the selected range will be filled.
if option "width" is specified, each bin content is multiplied by its Y bin-width during projection
Using a TCutG object, it is possible to select a sub-range of a 2-D histogram. One must create a graphical cut (mouse or C++) and specify the name of the cut between [] in the option. For example, with a TCutG named "cutg", one can call: myhist->ProjectionX(" ",firstybin,lastybin,"[cutg]"); To invert the cut, it is enough to put a "-" in front of its name: myhist->ProjectionX(" ",firstybin,lastybin,"[-cutg]"); It is possible to apply several cuts: myhist->ProjectionX(" ",firstybin,lastybin,"[cutg1,cutg2]");
NOTE that if a TH1D named "name" exists in the current directory or pad the histogram is reset and filled again with the projected contents of the TH2.
NOTE that the X axis attributes of the TH2 are copied to the X axis of the projection.

Compute the X distribution of quantiles in the other variable Y name is the name of the returned histogram prob is the probability content for the quantile (0.5 is the default for the median) An approximate error for the quantile is computed assuming that the distribution in the other variable is normal.
According to this approximate formula the error on the quantile is estimated as sqrt( p (1-p) / ( n * f(q)^2) ), where p is the probability content of the quantile and n is the number of events used to compute the quantile and f(q) is the probability distribution for the other variable evaluated at the obtained quantile. In the error estimation the probability is then assumed to be a normal distribution.

Slices a histogram in place based on the specified bin ranges for each dimension.
This function modifies the histogram by extracting a sub-region defined by the provided bin ranges for each dimension. The resulting histogram will have updated bin counts, edges, and contents. Bin contents outside the range fall into the flow bins. The histogram's internal data array is freed and reallocated by this function. This function is used by the python implementation of the Unified Histogram Interface (UHI) for slicing.
| ValueType | The type of the histogram's data. |
| args | A vector of integers specifying the low and upper edges of the slice for each dimension. |
| dataArray | A pointer to the histogram's data array. |
| fN | The size of dataArray. |
Smooth bin contents of this 2-d histogram using kernel algorithms similar to the ones used in the raster graphics community.
Bin contents in the active range are replaced by their smooth values. The algorithm retains the input dimension by using Kernel Crop at the input boundaries. Kernel Crop sets any pixel in the kernel that extends past the input to zero and adjusts the normalization accordingly. If Errors are defined via Sumw2, they are also scaled and computed. However, note the resulting errors will be correlated between different-bins, so the errors should not be used blindly to perform any calculation involving several bins, like fitting the histogram. One would need to compute also the bin by bin correlation matrix.
3 kernels are proposed k5a, k5b and k3a. k5a and k5b act on 5x5 cells (i-2,i-1,i,i+1,i+2, and same for j) k5b is a bit more stronger in smoothing k3a acts only on 3x3 cells (i-1,i,i+1, and same for j). By default the kernel "k5a" is used. You can select the kernels "k5b" or "k3a" via the option argument. If TAxis::SetRange has been called on the x or/and y axis, only the bins in the specified range are smoothed. In the current implementation if the first argument is not used (default value=1).

Write this object to the current directory.
The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".
Writing an object to a file involves the following steps:
Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.
If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().
The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.
An object is read from the file into memory via TKey::Read() or via TObject::Read().
The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.
