Can Xcode draw a graph of program calls?

Question

I'm new to Mac OSX, and I'm wondering if Xcode can generate a graph of program calls visually for a given C ++ source code.

I also wonder if, for each function, and after running it, it can also print% of the time spent on the function

If so, I would really thank some links with tutorials or information, after googling I did not find anything relevant

thank
