Dynamic Chart That Allows for Manipluation of Both, X and Y, Axis from Drop-Down List

Can anyone help me to create a dynamic chart that lets a user manipluation both, X and Y, axis from drop-down list? I have already figured out how to create a dynamic chart that allows me to manipulate the Y-axis from a drop down, but I cannot figure out how to include the X-axis.

I have attached an example of the file I am currently working with. Presently, I am able to switch between "Distance" and "ROP" on the Y-axis, with "Type" on the X-axis. However, my goal is to move add "Hours" to the X-axis as an alternative to "Type" ("Hours" is currently an Y-axis alternative, but again I want it on the X-axis).

Thanks in advance for your time! Tisha
