P Chart - show zones and shade zone option do NOT work?<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

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?

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

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.

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

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