Compute the average

2015	2016	2017	2018	2019	Sum	Average
-80	-78	-72	-64	-55	-349.0	-69.8

Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: -39.8

Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: -99.8

For the lines, you have the data necessary to plot the chart.
