Here is the script. I developed it by setting up the components I wanted interactively and then having JMP spit out the script. Right click on the moving average axis, and select Remove. Click on the graph and select Custom, and then changing the color of the upper, lower and average lines to white and 0 width. I also moved them up on the list to bury them into the background.
