Create a Pareto Chart in MS Excel 2010
Pareto Analysis is a simple technique for prioritizing potential causes by identifying the problems. The article gives instructions on how to create a Pareto chart using MS Excel 2010.
Steps
- Identify and List Problems. Make a list of all of the data elements/work items that you need to prioritize using the Pareto principle. This should look something like this.
- If you don't have data to practice, then use the data shown in the image and see if you can make the same Pareto chart, which is shown here.
- Arrange different Categories in Descending Order, in our case “Hair Fall Reason” based on “Frequency”.
- Add a column for Cumulative Frequency. Use formulae similar to what is shown in the figure.
- Now your table should look like this.
- Calculate total of numbers shown in Frequency and add a column for Percentage.
- Ensure that the total should be same as the last value in Cumulative Frequency column.
- Now your data table is complete and ready to create the Pareto chart. Your data table should look like this.
- Go to Insert-->Column and select the 2-D Column chart.
- A blank Chart area should now appear on the Excel sheet. Right Click in the Chart area and Select Data.
- Select Column B1 to C9. Then put a comma (,) and select column E1 to E9.
- This is one of the important step, extra care need to be taken to ensure correct data range is being selected for the Pareto.
- Now, your Pareto Chart should look like this. Frequency is shown as Blue bars and Percentage is shown as Red bars.
- Select one of the Percentage bars and right click. Click on “Change Series Chart Type” to “Line with Markers”.
- Following screen should appear.
- Now your chart should look like this.
- Percentage bars are now changed to line-chart.
- Select and right click on the Red Line chart for Percentage and Click on Format data series.
- Now, Format Data Series pop-up will open, where you need to select "Secondary Axis".
- Secondary "Y" axis will appear.
- The only problem with this Pareto Chart is the fact that the secondary Y-axis is showing 120%. This needs to be corrected. You may or may not face this issue.
- Select the Secondary Y-axis. Right click and click on "Format Axis" option shown as you right click.
- Go to Axis Options in the "Format Data Series" dialog box and Change the value for "Maximum" to 1.0.
- Your Pareto is complete and should look like this.
- However, you can still go ahead and Add some final touch to your Pareto to make it more appealing.
Go to Chart Tools --> Layout. You can add Chart Title,Axis Title,Legend and Data Tables, if you want.
- However, you can still go ahead and Add some final touch to your Pareto to make it more appealing.
