We want to show a control chart that has independent control limits for multiple conditions over time. For example, we recalibrated our analytical tool and we negotiated with the customer to shift the mean of the control limits. Then we switched to a different analytical tool while the original tool was down, and the backup had its own set of control limits. We learned that we can use "phase" to show multiple sets of control limits for different time periods, but only if they are auto-calculated. Can we specify hard limits for different conditions over time using phase?
Another example would be, we update our control limits quarterly and then they stay fixed for the entire quarter. Can we use phase to show changes in the control limits at discrete points in time without having jmp calculate the control limits on its own?
Thanks!
