Chart overlay

Question

I want to know if this is possible using the Google Graphics API. First create a histogram with input data. Then lay on top of it a line chart (or line).

My use case is to show student performance in a test compared to the rest of the audience, which is already available as a bar graph.

EDIT: Dug and found out about the markers. Will study and can answer my own question :)
