Hi, I was wondering if it is possible to Eval a spline fit. TGraph *gr = new TGraph(100,*x, *y); gr->Draw("apl"); The l has made a nice spline fit from x=0 to x=100 for example. Now, I want to get the value from the spline line at say x=53.2 Something like: gr->FindObject("spline")->Eval(53.2); Thank you, Kevin ------------------------------------------- - Kevin Reil - - #244A INSCC - - http://www.physics.utah.edu/~reil - - reil@physics.utah.edu - ------------------------------------------- - And my father dwelt in a tent. - -------------------------------------------
