CL used to control the grid in a graph?

I would like to be able to control the grid on a graph using CL (like a user button to turn on or off the grid). I realize I can make a “fake” grid, however I don’t know if you can control the thickness of the fake grid lines-- which is really nice. I also realize I could stack two graphs, one with the grid lines turned on and another with them off, then use a button to hide/show the graphs-- but that is pretty clunky. Other ideas?

Did you ever find the solution to turn the grid on and off? Sounds perfect for me.

You can use variables to define numeric values you find in the parameters, so, yes, you can control the thickness of your grid lines. I’ve used it to give students control of font sizes.
