Hey there,
So to briefly explain my situation, I used to have two TH1F’s, one as the main plot, and another as a subplot, which showed the ratio of two variables from the main plot using the Divide function. Binomial errors were propogated automatically, and calling the draw function of the ratio plot with Draw(“E0”), drew all points, even those off of the y-axis (I needed to zoom in to a region or else the spectrum would look simply flat, however for a few points that were outside this window it was important that the errors bars which did reach down into that range were seen).
Then I had to move from simple binomial errors to poisson errors. I did this by creating two TGraphAsymmErrors from the two original TH1F’s that went into making the ratio plot, calculating the upper error, nominal, and lower error on each. I then combined these errors and created another TGraphAsymmErrors which I filled with the poisson upper ratio error, nominal ratio, and poisson lower ratio error. (Maybe I am giving too much information but I just want it to be clear that I am doing everything for a purpose).
I now want to plot this TGraphAsymmErrors of the Ratio, in the same way I did with my old TH1F ratio, however using Draw(“ep0”) or Draw(“p0”) does not draw the points off of the y-axis scale like Draw(“e0”) did before, nor does it show the errors associated with these points which should still be visible even though the nominal points are not, so it appears I am unable to do this (I have already looked in root.cern.ch/root/html/TGraphPainter.html).
Is there anyway I can achieve this?
Best Regards,
Dan
