How to Make a Donut Chart in Excel

Use a Pie Chart when you have one data series and a Doughnut Chart for two or more series of data.

The charts below were made using this medication errors data.

The doughnut chart displays data in columns B and C. Errors for Baseline data in column B are on the inner ring and errors for column C are on the outer ring.

Pareto Charts for More Advanced Analysis

As you can tell, a doughnut chart is fairly 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 data is the Pareto Chart. It's hard to create a Pareto Chart in Excel, but its easy using an add-in like QI Macros. Just select your data, click on the QI Macros menu on your Excel tool-bar 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 Wrong Technique (the first and biggest bar) with 41 errors accounted for 45.1% of baseline Medication Errors. If we focus on just this type of error, we will be addressing almost half of the errors. The after 6 month pareto shows Wrong Technique as the second biggest bar at only 5 errors, accounting for only 23% (70% - 53.3%) of the total. An improvement team must have figured out a way to prevent many of the errors due to wrong technique!
