Above is the total information of the combined root file; Then I ues the root fit to do fit for the different set data and want to plot the post fit result (include the signal and bkg all like the globalObservable),but now I just get the below graph.

How to plot fitresults (sig and bkg(all)) together such as set1_data and the bkg belong to set1.
