Line graph over a histogram

[joeholiday]

At the risk of sounding a little dumb, does anyone know how to put a line graph over the top of a normal histogram?

There used to be a little button to click which basically did it for me but I'm now working on this new fangled excel (windows 7) and it's rather confusing!

Many thanks
Joe
