The problems remaining are that this does not produce a scatter plot, and the line
c1->Draw();
produces an error (“Unkown binary” is displayed repeatedly).
Also, ROOT is not accepting
Int_t n = 11000;
Double_t x[n];
The declaration of n (first line) is okay, but it says I cannot declare a Double_t when n is of a variable type. So I have to go Double_t = x[11000]; Could this be causing problems?
