A pareto chart is a basic quality management tool that displays the area of data you're collecting. Typically, the right vertical axis is the percentage of total number of occurances (totalling 100%). The left vertical axis is usually frequency of occurance, but could be cost or any other major descriptor you may be using to measure. The pareto chart looks similar to a bar chart, however, each "bar" of information added together equals 100%. Also, included in the chart is a line graph showing the cumulative total of each category.
This chart is used most often to point out the points of negative growth. IE reasons for customer complaints, employee dissatisfaction, or lack of productivity.
You can create this type of chart using Microsoft Office Suite.
