Are the fraction/whole number/decimal, etc... actually the same value but different types of numbers?  If so, I'd group them together and have it dynamically shown on the graph.  

Having it on line graph also allow for multiple types of values easily viewed.  Take inspiration from Facebook Pages' Analytic! 

Here's a quick wireframe I did up.  ![Graph Sample][1]
