Consider a Pareto Chart for More Advanced Analysis
Pie charts are popular charts, but if you have too many categories they can become difficult to read. If you look at the chart above: Is there a problem? What is it? What action should you take?
A much better chart to analyze this kind of data is the Pareto Chart. It's hard to create a Pareto Chart in Excel, but its easy using QI Macros add-in for Excel. Just select your data, click on the QI Macros menu on your Excel toolbar and select Pareto Chart. QI Macros will do all of the math and draw the chart for you.
Interpreting the Pareto Charts
QI Macros Pareto chart tells us that TH Void accounted for 16 of the defects which was 25.8% of the total. If we focus on just this category, we will be addressing over 1/4 of the defects. The pareto chart also automatically summarizes the defects with lower quantities into an "Other" category to help keep the chart easy to read.
