Is there a way to project the integral over x:
RooFormulaVar f(“f”, “f”, “xyz”, RooArgSet(x, y, z));
(RooAbsReal* integral = f.createIntegral(RooArgSet(x), “R0”);
of a RooFormulaVar dependent on x, y and z, in the variables y and z? Just like a TH2F in Root?
As far as I know I can create a frame on a single variable:
RooPlot* frame = y.frame(Title(“Integral of f over x in region R0”)) ;
Is there a way to create a 2D frame?
