[ROOT] Spline, tgraph and function fit

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
