You can interactively select the Menu Edit->Editor.
Then you get a self-explaining toobox with wich you can put objects on
you already draw histo.

Then, just use the File->Save As canvas.C and have a look on the
generated file : You'll get full code of what you just interactively
done.

At that point, you can go to the ROOT Class & Member Reference Guide to
perfect your knowledge of the Class (TLine, TEllipse etc) you just
discovered.
