Hello experts,
I am doing a fit with roofit and I want to draw also the fit pulls. As per their definition, they should not have error bars.
I have a RooRealVar deltaE
and a RooPlot xframe
on which I plot an histogram and the result of a fit. I then do
RooPlot *pull1_frame = deltaE.frame();
RooHist* hpull1 = xframe->pullHist();
pull1_frame->addPlotable(hpull1,"p");
but the resulting histogram is drawn with error bars, even though I use the “p” option only.
Can anybody suggest me the trick to draw this histogram without it’s error bars?
