This is the part where you can see what all your hard work has been leading to. The charts.

2. Enable Zones.
The chart now looks as follows:
The colored zones identify how far each datapoint is from the target value.
The zones work as follows:
0-1 sigma from target value
1-2 sigma from target value
>2 sigma from target value
These sigma values are used to calculate whether or not a system is in control.

4. Click the cross in the top-right corner to close the Subgroup Info popup.
