Thank you for you help.

TCanvas *c= new TCanvas("smth","smth", 10,20,200,400);
	Double_t x[] = {26,38,41,42,44,47,48,51,53,55,58,59,61,63,65,67,69,71,73,75};
	Double_t y[] = {1.2424e+012,7.7958e+010,3.4829e+010,1.70323e+010,9.3366e+009,5.31988e+009,3.26232e+009,1.97405e+009,1.2783e+009,9.0085e+008,6.9448e+008,5.65103e+008,5.007e+008,4.25601e+008,3.43924e+008,2.870635e+008,2.4560e+008,2.11328e+008,1.17601e+008,1.161475e+008}

TGraph *g = new TGraph(20,x,y); 

You are missing a “;” character in the end of the “Double_t y[] …” line.

BTW. When you post “source code” or “output” here, do remember to enclose them into two lines which contain just three characters ``` (see how your post has been edited above).
