Looking for some assistance with getting parameters and having them control values

[Chronichurdle]

Hello, I am slowly starting to understand the way lua works within DCS, and I have a "simple" idea. I would like to get the Horizontal Acceleration value, and have it represented on a scale on the controls indicator. Like the SU27 acceleration meter, but continuous, so not 0, 1, 2  states

Could someone with more experience explain where they would maybe start? I can learn how to do it, but I just need some guidance linking it all together. 

Thankyou
