Replace all references to Axis_t and Stat_t by Double_t in all histogram classes.
Following several recent requests, implement new functions
to search the bin with a specified content.
Double_t TH1::GetBinWithContent(Double_t c, Int_t &binx, Int_t firstx, Int_t lastx,Double_t maxdiff) const
{
// compute first binx in the range [firstx,lastx] for which
// diff = abs(bin_content-c) <= maxdiff
// In case several bins in the specified range with diff=0 are found
// the first bin found is returned in binx.
// In case several bins in the specified range satisfy diff <=maxdiff
// the bin with the smallest difference is returned in binx.
// In all cases the function returns the smallest difference.
//
// NOTE1: if firstx <= 0, firstx is set to bin 1
// if (lastx < firstx then firstx is set to the number of bins
// ie if firstx=0 and lastx=0 (default) the search is on all bins.
// NOTE2: if maxdiff=0 (default), the first bin with content=c is returned.
Double_t TH2::GetBinWithContent2(Double_t c, Int_t &binx, Int_t &biny, Int_t firstx, Int_t lastx, Int_t firsty, Int_t lasty, Double_t maxdiff) const
{
// compute first cell (binx,biny) in the range [firstx,lastx](firsty,lasty] for which
// diff = abs(cell_content-c) <= maxdiff
// In case several cells in the specified range with diff=0 are found
// the first cell found is returned in binx,biny.
// 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 firstx <= 0, firstx is set to bin 1
// if (lastx < firstx then firstx is set to the number of bins in X
// ie if firstx=0 and lastx=0 (default) the search is on all bins in X.
// if firsty <= 0, firsty is set to bin 1
// if (lasty < firsty then firsty is set to the number of bins in Y
// ie if firsty=0 and lasty=0 (default) the search is on all bins in Y.
// NOTE2: if maxdiff=0 (default), the first cell with content=c is returned.
Double_t TH3::GetBinWithContent3(Double_t c, Int_t &binx, Int_t &biny, Int_t &binz, Int_t firstx, Int_t lastx, Int_t firsty, Int_t lasty, Int_t firstz, Int_t lastz, Double_t maxdiff) const
{
// compute first cell (binx,biny,binz) in the range [firstx,lastx](firsty,lasty][firstz,lastz] for which
// diff = abs(cell_content-c) <= maxdiff
// In case several cells in the specified range with diff=0 are found
// the first cell found is returned in binx,biny,binz.
// In case several cells in the specified range satisfy diff <=maxdiff
// the cell with the smallest difference is returned in binx,biny,binz.
// In all cases the function returns the smallest difference.
//
// NOTE1: if firstx <= 0, firstx is set to bin 1
// if (lastx < firstx then firstx is set to the number of bins in X
// ie if firstx=0 and lastx=0 (default) the search is on all bins in X.
// if firsty <= 0, firsty is set to bin 1
// if (lasty < firsty then firsty is set to the number of bins in Y
// ie if firsty=0 and lasty=0 (default) the search is on all bins in Y.
// if firstz <= 0, firstz is set to bin 1
// if (lastz < firstz then firstz is set to the number of bins in Z
// ie if firstz=0 and lastz=0 (default) the search is on all bins in Z.
// NOTE2: if maxdiff=0 (default), the first cell with content=c is returned.
