Hi Anthony, I have implemented a new option in TH1::Draw(option) So far, when option "same" was specified, the function PaintStat was not called. If now you specify the option "sames", this function will be called. I have added the following comments in the doc. // // When option "same" is specified, the statistic box is not drawn. // Specify option "sames" to force painting statistics with option "same" // When option "sames" is given, one can use the following technique // to rename a previous "stats" box and/or change its position // Root > TPaveStats *st = (TPaveStats*)gPad->GetPrimitive("stats") // Root > st->SetName(newname) // Root > st->SetX1NDC(newx1); //new x start position // Root > st->SetX2NDC(newx2); //new x end position // Root > newhist->Draw("sames") Rene Brun Anthony Faust wrote: > > Another email with the same subject went out a few months ago but there > was no answer published to the group, so I thought I would try it again as it is > something I am also interested in. > > How does one plot two or three histograms in the same > frame (using Draw("same")) and get the statistics box for all histograms? > I tried to replicate the relevent parts for THistPainter but could not get this > to work. > > Another more drastic option would be to change the conditional in > THistPainter::Paint > > if (!Hoption.Same) { > TF1 *fit = (TF1*)fFunctions->First(); > if (!fH->TestBit(TH1::kNoStats)) { // bit set via TH1::SetStats > PaintStat(gStyle->GetOptStat(),fit); > } > } > > to make showing all stats boxes the default behaviour, set with TH1::kNoStats, > > if ( !fH->TestBit(TH1::kNoStats) ) { // bit set via TH1::SetStats > TF1 *fit = (TF1*)fFunctions->First(); > PaintStat(gStyle->GetOptStat(),fit); > } > > and have these TNamed objects created with unique names, such as hist1stat, > hist2stat, etc., which could then be accessed by a mouse click on the histogram > or other user code. > > _____________ > Dr. Anthony A.
