Control Chart - JMP 15

[#1]

I just updated JMP to 15 version.

I do not know how to create the time line on Individual and Moving Range Control Chart.

Also my table have category data that I can create Individual chart for each in one chart as I can do in JMP 14. I do not know how to do this in JMP 15.

Any helps will be much appreciated and thanks.
