Hey watcha guys using to plot the possibilties of your 4 link bars in the different holes?

Im getting ready to weigh the car and calculate the CG of my car. Using the formulas from Dave Morgans book.

I would also like to know what all the combos would be from moving the 4 link bars?

I know you can plot it out on the wall or big piece of paper. But what a about a computer program?
