P Chart - show zones and shade zone option do NOT work?

tajrida

Using the washer.JMP (sample data file) I created a P-chart and selected "show zones" and "shade zones" option in red triangle. Nothing happens....

Why?

Could it be that your sample sizes are not all the same? When sample sizes are unequal you can't show the zones because they're non-constant.

FYI: My version of JMP is 12.0.1

Strange. I run the same version (for Mac) and the commands works for me.

This is so strange.. Tried the commands on "washer.JMP" today and found they are working.

Next...

Tried same commands on other P-charts created using company and internet data and nothing works.

Don't know what I am doing wrong or may be a glitch in software
