process performance graph: removing Cpk 1.33 curve

Question

This is driving me nuts, how do I remove the red Cpk=1.33 curve from the graph.  Is there any value in keeping this (given that most of my processes are not stable!!, therefore Cpk is not sensitive to non stable processes).  I do not get what info it gives me given my lack of statisitcal control, thanks in advance

You might want to put this on the JMP Wish List in the menu of the community window. Please add also the reason why you would like to be able to change this line as this helps better to understand your needs.

I do not see a direct way to eliminate the Cpk line.  However, you can hide the line, by moving it behind all of the other objects on the graph.  To do this:

* Right click on the graph and select "Customize"
* Select the "Cpk=1.33" object
* Move the object to the top of the stack of objects

Other community members may have a better solution, but at least this gets the graph close to what you want.
