Revision Log
Import changes from math development branch, in particular a re-implementation of
fitting methods for the histogram and graph objects.
NOTE: Since some files are removed, a make clean-hist is needed in order to be able
to compile hist after an svn update.
The implementation of TH1::Fit, TGraph::Fit, TGraph2D::Fit and TMultiGraph::Fit is
done in a common function implemented in HFitImpl.cxx (HFit::Fit).
In addition the file HFitInterface.h define ROOT::Fit::FitObject functions passing
option directly via Foption class and not by a string. They are used by the FitPanel.
Remove previously existing files THistFitInterface.cxx (and *.h) and
TGraphFitInterface.cxx (and *.h). The code is now in the HFitInterface.cxx (and *.h)
files.
Use plugin manager directly to open the Fit Panel. Do not pass anymore via the THistPainter.
Changes in TH1::FitPanel, TGraph::FitPanel.
Add FitPanel() method for TGraph2D and TMultiGraph.
Add new class TBackCompFitter, providing a backward compatible implementation of
TVirtualFitter using the new fitting class. It is constructed from the fitter class
and can be used to retrieve the fit information (result and configuration) via the
TVirtualFitter API from FitConfig and FitResult. A static istance is created after
calling the Fit method.
Other changes are:
TGraph:
- when creating a graph from an histogram, don't use the same name.
Otherwise it will conflict later with histogram created internally by the TGraph.
TH2:
add protected method TH2::DoFitSlices and TH2::DoProfile as common implementations
for (FitSlicesX,FitSclicesY) and (ProfileX, ProfileY).
pass the global statistics in DoProjection when range is (1,NBIN)
TBinimialEfficiencyFit:
add possibility to set verbose option, and set different precision and
max iterations for minimizing.
