Ever struggled with large sets of data and wondered how to make sense of it all? I’ve been there too. That’s when I discovered the magic of Pareto charts. They’re a fantastic tool to identify and prioritize problem areas in a process or system, right from your Excel spreadsheet.
Creating a Pareto chart in Excel might seem daunting at first, especially if you’re not a data whiz. But don’t worry, I’ve got your back. I’ll walk you through each step, ensuring you’ll be able to create your own Pareto charts in no time.
So, whether you’re a seasoned Excel user or a complete newbie, this guide will make the process of drawing a Pareto chart a breeze. Let’s dive in, shall we?
Understanding the Pareto Principle
Before we dive deeper into creating Pareto charts in Excel, it’s crucial to understand the Pareto Principle itself. Also known as the 80/20 rule, the principle was introduced by an Italian economist Vilfredo Pareto. He observed that about 80% of the land in Italy was owned by 20% of the population. This observation led to the creation of the Pareto Principle, a concept which suggests that roughly 80% of effects come from 20% of the causes.
In the world of business and quality management, we often find that around 80% of our problems are caused by 20% of the issues. These are our major players, the ones that really impact our processes. By targeting these issues, we can create meaningful improvements. This is where Pareto charts come in. They help spotlight these key problem areas, so we can prioritize our resources and actions.
When creating Pareto charts, this key 80/20 metric is integral. The charts graphically represent the correlation of cause and effect, which allows us to better analyze and optimize our problem-solving process.
Next, after understanding the theory behind the Pareto Principle, we’re going to look at how we can utilize Excel to visualize this principle via Pareto charts. We’ll walk through each step of the process, making sure you comprehend each move, regardless of your level of Excel proficiency.
Preparing Your Data in Excel
Before we plunge headfirst into creating a Pareto chart, it’s important to sort our data. Organizing the data isn’t just about making it look neat—it’s about laying the groundwork for accurate and meaningful graphs.
First and foremost, gather the data you’re going to be working with. Pinpoint what causes you’re investigating and gather the relevant effects data. For example, if you’re looking to improve the quality output in a manufacturing process, you’d gather data on defects—their frequency or severity, for instance.
Once you have your data, it needs to be organized in Excel. Start by placing your causes in the first column and corresponding effects in the second. Usually, I like to label these as ‘Cause’ and ‘Effect’ respectively for clarity’s sake. Here’s what a basic setup should look like:
| Cause | Effect |
|---|---|
| Cause 1 | Effect 1 |
| Cause 2 | Effect 2 |
| Cause 3 | Effect 3 |
(Take note that these labels are arbitrary. They might change depending on the nature of your study.)
However, setting up a Pareto chart doesn’t stop there. One key aspect is arranging your data in descending order based on the effect. So, where ‘Effect 1’ is the largest effect, followed by ‘Effect 2’, and so forth. This ordering represents the application of the 80/20 rule; that’s to say, the highest-ranked causes will be your vital few that contribute to the larger share of effects.
Having organized data in Excel is a vital pre-step that streamlines the creation of your Pareto chart. After all, a chart is only as good as its underlying data—and getting your data in shipshape, can save you a lot of tweaking down the line.
In the next section, let’s take these organized data and plug it into Excel’s default chart wizard, which will guide us through creating a stand-out Pareto chart for your quality improvement needs.
Creating a PivotChart in Excel
Now that we’ve culled and sorted our data, it’s time to pivot towards the actual creation of your Pareto Chart. While Excel doesn’t have a built-in Pareto chart option, we can use a PivotChart to emulate one. Why’s that you ask? It’s because a PivotChart aligns itself perfectly with the 80/20 rule, showcasing what issues need to be tackled first and where we’re getting the most impact!
Setting Up the PivotTable
This is the stage where our refined and sorted data gets to truly shine. Start by selecting your data then head to the Insert tab and choose PivotTable. This will create a new worksheet for your PivotTable. The rows are causes or factors contributing and the values are the effects or issues experienced.
Once your PivotTable is set up, we will then work on the PivotChart. Go to the Analyze tab and choose PivotChart from the options.
- PivotChart Type: Here, select the column chart type.
- Sorting: Sort the fields once again by descending effect size.
Salient points to remember for setting up the PivotChart include:
- Make sure to include both a series and a cumulative series in the chart.
- The latter should be a line chart type, conveying the “80%” part of the Pareto Principle.
- For a crisp visual presentation, the primary and secondary vertical axes should be aligned.
Effectively leveraging Excel’s PivotChart function makes it incredibly easy to create a Pareto chart, even without a dedicated option for it. Using a PivotChart will efficiently highlight the most critical causes and provides a visual aid that brings the Pareto Principle to life. The process of setting up and using a PivotChart is intuitive and quick, making it an essential tool in your data analysis toolkit.
There’s so much more to explore and leverage in this program, and I’m here to guide you every step of the way. Let’s delve deeper to ensure we optimize your data presentation skills through Excel. The next section will tackle how to customize and finetune your PivotChart in order to draw meaningful insights from your data.
Adding Pareto Line to the Chart
The next step in our journey to build a dynamic Pareto chart in Excel is a vital one: we’ll add a Pareto line. This line amplifies our chart by representing cumulative percentages, allowing us to visualize the 80/20 rule directly. So, how exactly do we do that? It’s simpler than you might assume.
After creating the PivotChart, it’s essential to add a secondary axis for our Pareto line. Click on any data bar in the chart, then click on Design and Change Chart Type. Go beyond the typical column chart and choose Combo, which lets us combine chart types. In this mix, select Clustered Column for frequency count and Line for cumulative percentages. Don’t forget to tick Secondary Axis for the line chart.
With the line chart added onto a separate axis, you will immediately see the power of our Pareto chart take effect. The cumulative percentages climb, highlighting the most significant causes right up front.
There’s a little more refining we can do to solidify our chart’s effectiveness. By default, Excel’s line chart includes markers. We don’t need these, as they may clutter our visual. To get rid of them, click on the Pareto line, access Format > Shape Outline > No Outline. This small step drastically increases our chart’s clarity and professionalism.
A pro tip: consider chart style and color scheme when presenting your data. Different styles and colors can impact readability and how individuals perceive your visual representation. Experiment with these settings to figure out what works best for your data.
Hopefully, the application of these practical steps will have you efficiently creating Pareto charts with ease. We have covered essential steps such as adding a secondary axis and removing unnecessary markers. There are more options available for customization and refinement, and I encourage you to explore.
There’s no conclusive point here, just an invitation to add more value to your data presentation skills. Polish your Excel expertise and make your Pareto charts most effectively reflect your critical data points.

What is the 80/20 rule in a Pareto chart?
The 80/20 rule, also known as the Pareto Principle, is a tenet stating that 80% of outcomes (or outputs) result from 20% of all causes (or inputs) for an event. In a Pareto chart, this relationship is often symbolized by a cumulative line.
