#### XMR(3) Chart

An XMR Chart that plots the ranges between pairs of successive data points. In an XMR(2) Chart, the range between points 1 and 2 would be plotted, then the range between points 2 and 3, then the range between points 3 and 4, and so on. Two additional statistical parameters, CP and CPK, also appear on the chart.
