Possible? Raw # Graph data w/ % labels??

[jgoins]

Greetings!

I am wondering if this is possible or not- I have a table of raw data that I have made a line and bar graph from...What I would like to do is keep the graphs as they are (with the y-axis based on the actual raw data numbers), but then instead of the data labels reflecting that actual raw number as they currently do, I'd like it to reflect what percentage that raw number represents out of the grand total...clear as mud?

Any idea if this is possible?

Thanks so much for the help! I have attached a sample of the data in case that helps!!
