Control Charts are considered to be one of the Seven Basic Tools of Quality. They are helpful in Quality Control Management to show if a process is in or out of control. The principle to drawing a Control Chart is fairly straight-forward, but it is not so easy to do in Excel because you need to add lines for Upper Control Limits (UCL), Lower Control Limits (LCL) and a Central Line (CL).
The video below shows a way to work around this by plotting four sets of data. The first is that actual data representing the quality measurements, the other three are "cheats". For each data point representing the measurements, plot the Mean, Standard Deviation + 3, and Standard Deviation - 3, in other words the same value over and over. This gives us straight lines as shown in the video. Check it out and see what you think:
