Dynamically set graph axis min/max levels

I created an excel file that provides a rotor balancing solution based on vibration data runs.
It uses a graphical display similar to GPS signals to locate a receivers location.
Essentially, it displays 4 circles on a polar plot.

To show properly, the X and Y axis must have the same min/max, so I "fixed" the axis properties to -10/+10
The problem is that if the user data is higher than "10", the user is then forced to manually change both X and Y axis accordingly to visually fit the circles on the graph.

I was hoping there was a way to add a "slider" control that would dynamically change the X and Y axis bounds of the graph.
Has anyone done something like this?

Thanks for your help
I created a small macro to do exactly what I wanted (re-size graph based on a cell value)
