Calibration X-Bar-R Chart
This chart provides a detailed review of a particular phase (e.g., zero, span, precision) for a
particular parameter over time. The top chart shows the measured response and expected /
reference value for each calibration event. If drift limits have been set, those bounds are
shown as well. The bottom chart shows the value of the drift (difference) from one cal event
to the next.
