A type of Individual Chart. X Moving Range Charts are control charts for the individuals (X) and the moving range (MR). The upper chart is similar to a Run Chart: it shows the individual values plotted against the control limits. The lower chart shows the moving ranges. Two kinds of XMR Charts are available: XMR(2) and XMR(3), where 2 and 3 indicate the sizes of the moving subgroups used for the range portion of the chart.
