Web r = the absolute value of the difference between successive pairs of measurements. If the r chart is out of control, then the control limits on the xbar. The and r chart plots the mean value for the quality characteristic across all units in the sample, , plus the range of the quality characteristic across all units in the sample as follows: Select the method or formula of your choice. If we supply a vector, the plot will have bars with their heights equal to. The chart actually consists of a pair of charts:
