How to create charts for each user's statistics?

I am working on a wordpress website that will allow members to sign up. I was wanting to create a dashboard where after users take something like a personality quiz it would show a chart of their results. Along with this dashboard I was hoping that these charts and other statistics could be saved per user, i.e. Joe see's his results and Sarah her's. Does anyone know of a plugin or outline how I might attempt this. Thank you.
