Hi, I want to put a graph, something like TGraphErrors(n,x,y,xErr,yErr), onto an existing histogram (TH1F), and shrink the graph a little to let it cover the upper-right corner of the histogram.
Can anyone give me some hint about how to do that? Thanks a lot !
I tried to output the graph and the hist individually as 2 eps pictures, then tried to use other softwares to put the graph onto the hist, but I can not keep the quality of the picture.
