Dear all,
I am trying to do an SPC chart where I wanted to show:
1. A run of x consequential points above the mean in one colour
2. A run of x consequential points below the mean in another.
3. If it is above or below UCL or LCL, then another colour.
4. The rest of everything in another.
I've almost done all of them but the only thing that doesn't work is the beginning and end month, which is not showing the right colours. Attached the files.
Any help is appreciated.
