virtualinherited

Project slices along Z in case of a 3-D histogram, then fit each slice with function f1 and make a 2-d histogram for each fit parameter Only cells in the bin range [binminx,binmaxx] and [binminy,binmaxy] are considered. if f1=0, a gaussian is assumed Before invoking this function, one can set a subrange to be fitted along Z via f1->SetRange(zmin,zmax) The argument option (default="QNR") can be used to change the fit options. "Q" means Quiet mode "N" means do not show the result of the fit "R" means fit the function in the specified function range

Note that the generated histograms are added to the list of objects in the current directory. It is the user's responsability to delete these histograms.

Example: Assume a 3-d histogram h3 Root > h3->FitSlicesZ(); produces 4 TH2D histograms with h3_0 containing parameter 0(Constant) for a Gaus fit of each cell in X,Y projected along Z with h3_1 containing parameter 1(Mean) for a gaus fit with h3_2 containing parameter 2(StdDev) for a gaus fit with h3_chi2 containing the chisquare/number of degrees of freedom for a gaus fit

Root > h3->Fit(0,15,22,0,0,10); same as above, but only for bins 15 to 22 along X and only for cells in X,Y for which the corresponding projection along Z has more than cut bins filled.

NOTE: To access the generated histograms in the current directory, do eg: TH2D h3_1 = (TH2D)gDirectory->Get("h3_1");

GetStats()

void GCube::GetStats ( Double_t * stats ) const

overrideinherited

fill the array stats from the contents of this histogram The array stats must be correctly dimensionned in the calling program. stats[0] = sumw stats[1] = sumw2 stats[2] = sumwx stats[3] = sumwx2 stats[4] = sumwy stats[5] = sumwy2 stats[6] = sumwxy stats[7] = sumwz stats[8] = sumwz2 stats[9] = sumwxz stats[10] = sumwyz

If no axis-subranges are specified (via TAxis::SetRange), the array stats is simply a copy of the statistics quantities computed at filling time. If sub-ranges are specified, the function recomputes these quantities from the bin contents in the current axis ranges.

Note that the mean value/RMS is computed using the bins in the currently defined ranges (see TAxis::SetRange). By default the ranges include all bins from 1 to nbins included, excluding underflows and overflows. To force the underflows and overflows in the computation, one must call the static function TH1::StatOverflows(kTRUE) before filling the histogram.

fXAxis.GetBinCenter(1) < x < fXaxis.GetBinCenter(nbinX) AND fYAxis.GetBinCenter(1) < y < fYaxis.GetBinCenter(nbinY) AND fZAxis.GetBinCenter(1) < z < fZaxis.GetBinCenter(nbinZ)

KolmogorovTest()

Double_t GCube::KolmogorovTest ( const TH1 * h2, Option_t * option = "" ) const

overrideinherited

Statistical test of compatibility in shape between THIS histogram and h3, using Kolmogorov test. Default: Ignore under- and overflow bins in comparison

option is a character string to specify options "U" include Underflows in test "O" include Overflows "N" include comparison of normalizations "D" Put out a line of "Debug" printout "M" Return the Maximum Kolmogorov distance instead of prob

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 more than 1D the order for generating the pseudo-CDF is arbitrary, we use the pseudo-CDF's obtained from all the possible 6 combinatons of the 3 axis. The average of all the maximum distances obtained is used in the tests.

Merge()

Long64_t GCube::Merge ( TCollection * list )

overrideinherited

Add all histograms in the collection to this histogram. 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 successfull, -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.

virtualinherited

-*-*-*Rebin this histogram grouping ngroup/ngroup bins along the xaxis/yaxis/zaxis together*-*-*-*-

if newname is not blank a new temporary histogram hnew is created. else the current histogram is modified (default) The parameter ngroup indicates how many bins along the xaxis/yaxis/zaxis of this have to me merged into one bin of hnew If the original histogram has errors stored (via Sumw2), the resulting histograms has new errors correctly calculated.

examples: if hpxpy is an existing GCube histogram with 40 x 40 x 40 bins hpxpy->Rebin3D(); // merges two bins along the xaxis, yaxis, and zaxis in one in hpxpy // Carefull: previous contents of hpxpy are lost hpxpy->Rebin3D(5); //merges five bins along the xaxis, yaxis, and zaxis in one in hpxpy GCube* hnew = hpxpy->Rebin3D(5,"hnew"); // creates a new histogram hnew // merging 5 bins of h1 along the xaxis, yaxis, and zaxis in one bin

NOTE : If ngroup is not an exact divider of the number of bins, along the xaxis/yaxis/zaxis the top limit(s) of the rebinned histogram is changed to the upper edge of the bin=newbins*ngroup and the corresponding bins are added to the overflow bin. Statistics will be recomputed from the new bin contents.

void GCube::SetShowProjection ( const char * option = "xy", Int_t nbins = 1 )

virtualinherited

When the mouse is moved in a pad containing a 3-d view of this histogram a second canvas shows a projection type given as option. To stop the generation of the projections, delete the canvas containing the projection. option may contain a combination of the characters x,y,z,e option = "x" return the x projection into a TH1D histogram option = "y" return the y projection into a TH1D histogram option = "z" return the z projection into a TH1D histogram option = "xy" return the x versus y projection into a TH2D histogram option = "yx" return the y versus x projection into a TH2D histogram option = "xz" return the x versus z projection into a TH2D histogram option = "zx" return the z versus x projection into a TH2D histogram option = "yz" return the y versus z projection into a TH2D histogram option = "zy" return the z versus y projection into a TH2D histogram option can also include the drawing option for the projection, eg to draw the xy projection using the draw option "box" do myhist.SetShowProjection("xy box"); This function is typically called from the context menu. NB: the notation "a vs b" means "a" vertical and "b" horizontal
