QI Macros Allow You to Create Multiple Pareto Charts at Once
- To create two or more Pareto charts using the QI Macros, select one column of labels and two or more columns of data (e.g., E2:G14 below to compare Line 1 and Line 2):

QI Macros will create a Pareto chart for each column of data you selected.
