Welcome to the Discussion Community,
Both the IMR and the Levey Jennings charts are reachable through the
Help=>Statistics Index
Or you can just go to
Analyze=>Quality and Process=>Control Charts=>IMR Control Chart
or
Analyze=>Quality and Process=>Control Charts=>Levey Jennings Control Chart
Select Raw Number as the Y axis and Batch Name as the Sample Label/Subgroup
I strongly suggest that you take the time to read the Discovering JMP document available under the Help pull down menu
