A type of chart that contains both bars and a line graph and displays the values in descending order as bars and the cumulative totals of each category, left to right, as a line graph. Its purpose is to highlight the most important among a (typically large) set of factors. In loss prevention evaluations it is used to display the number of failures of components by part number in descending order of failure rate or number of failures observed. Data may also be shown taking into account the total cost of each failure.
