Presently trying to manually set the control limits in Levey Jennings control chart since my data has a natural limit of LCL = 0. Can you please suggest how can I do it in JMP Pro 12?

Re: Setting Control limits manually for Level Jennings chart

Hi Jim,

Thank you for the solution

I have selected the CL, LCL and UCL columns and put in the following information as you have mentioned above

CL = 28907525.70

LCL = 0

UCL = 3648261306.71

But when I am clicking on Analyze<Quality and Process<Control Chart<Levey Jennings Control chart it is not taking my set limits. Can you please tell me where I am going wrong?

Re: Setting Control limits manually for Level Jennings chart

Is it possible that you set the UCL and LCL for XBar, or C Chart, etc. rather than for the Levey Jennings? I used the Semiconductor Capability data table from the Sample data tables, and set the Levey Jennings LCL to 0 and the UCL to 120 and then ran the Control Chart platform for Levey Jennings, and got the following results:
