Ratio plot of TGraphAssymError & histogram

Hi Experts,

                 Is it possible to draw ratio plots of TGraphAsymmErrors with histograms? I'm trying to do so but its it does not work.  OR I have to convert TGraphAsymmErrors firstly into histogram and then compare two histograms. I have attached the code with this thread. Please help.

Thanks…
