Drawing THStack

Dear experts,
if I have 5 bkg histograms and 1 signal histogram in a THStack, and I want to draw only the bkgs hist as stack, and just plot the signal (so no stack for the signal), is it possible? or am I obliged to put the signal in another histogram and use Draw(“same”)?

Yes you are.

Dear Couet,

ok, thank you for your answer.
