What is the 80/20 rule in a Pareto chart?

The 80/20 principle states that roughly 80% of outcomes come from 20% of causes. In a Pareto chart, you draw a horizontal reference line at 80% on the cumulative line axis. Every bar to the left of where the cumulative line crosses that threshold is in your vital few, the causes worth addressing first.

When should I use a Pareto chart?

Use a Pareto chart when you need to prioritize: customer complaints by frequency, defect types in manufacturing, bug categories in software, revenue by product, support tickets by reason. It answers the question: where should we focus to get the most impact?

Can I import data from Excel or Google Sheets?

Yes. Import from Excel or Google Sheets directly into the editor. Format: one column for categories, one column for counts or values. AECharts sorts automatically and calculates the cumulative percentage line.

What export formats are available?

Export as PNG, JPEG, PPTX, or MP4. All formats work in PowerPoint, Google Slides, and reports. Image export is available on all plans.

How many categories should a Pareto chart have?

Six to twelve categories works well. Fewer and there isn't enough to prioritize. More than fifteen and the chart becomes hard to read. Consider grouping the tail into an Other category.

What is the difference between a Pareto chart and a bar chart?

A standard bar chart shows values. A Pareto chart adds two things: the bars are sorted largest to smallest, and an overlay line shows the cumulative percentage. That line is what makes Pareto useful. It tells you exactly which bars, combined, account for 80% of the total.

Do I need design skills?

No. Templates are professionally designed. Import your data and the chart builds automatically. Most users create their first Pareto chart in under two minutes.

Is there a free plan?

Yes. All features are free with unlimited image exports. Video exports at 1080p require a Pro plan starting at $19/month billed annually. No credit card required to start.

Can I use a Pareto chart in a presentation?

Yes. Export as PNG, PPTX, or MP4 and drop directly into PowerPoint or Google Slides. Pareto charts are particularly effective in quality reviews, retrospectives, and strategic planning sessions where you need to justify focus areas with data.

Is there a free Pareto chart generator online?

Yes. AECharts is a free Pareto chart generator. Open the editor, select Pareto Chart, paste your data, and export as PNG, JPEG, PPTX, or MP4. Bars are sorted and the cumulative line is calculated automatically. No design skills or account required to start.

What is a Pareto diagram?

A Pareto diagram is another name for a Pareto chart. Both refer to the same visualization: bars sorted largest to smallest with a cumulative percentage line overlaid. The terms Pareto chart, Pareto diagram, Pareto graph, and 80/20 chart all describe the same tool for identifying which causes account for most of an effect.

Q: What is a Pareto chart?

A Pareto chart combines a descending bar chart with a cumulative percentage line. It applies the 80/20 rule, identifying the small number of causes that account for the majority of an effect. The bars rank categories from largest to smallest; the line shows the running total so you can see where you cross 80%.

A Pareto chart, also called a Pareto diagram or Pareto graph, combines bars sorted largest to smallest with a cumulative percentage line. It makes it easy to identify the small number of causes that account for the majority of an effect. Build Pareto charts online from your Excel or Google Sheets data for quality reviews, defect analysis, and prioritization. Free to start.

How to Create a Pareto Chart

Select the Pareto chart type

Open the AECharts editor and select Pareto Chart from the chart type picker. If you want a different visual style, browse the template explorer on the right panel and click any template to apply it instantly.

Enter your data

Click "Edit Data" in the top-right corner to open the spreadsheet. Add category names in the first column and values in the second. No need to sort — AECharts automatically orders bars from largest to smallest and computes the normalized cumulative percentage line. Import directly from Excel or Google Sheets, or upload a CSV or Excel file.

Adjust styling

Use the top menu bar to customize the look. Set bar color, stroke color, stroke width, and bar width. Adjust the cumulative line color and width separately. The usual label, tick, axis, and grid options — font, size, and color — are all available too. Every change previews instantly.

Export

When you're ready, export as a static image (PNG), an animated video (MP4 at 1080p), or a PowerPoint file. MP4 embeds directly into slides and social posts; PNG works for reports and print; PPTX lets you keep editing in PowerPoint.

When to Use a Pareto Chart

Pareto charts work best when you need to prioritize. When you have multiple causes or categories and want to know which ones deserve attention first.

Customer Complaints

Rank complaint types by frequency. The top two or three categories almost always account for the majority. Fixing those has the highest leverage.

Defect Analysis

In manufacturing and QA, Pareto charts reveal which defect types are responsible for most failures. Standard tool in Six Sigma and lean processes.

Support Ticket Triage

Show which ticket categories consume the most engineering time. Makes the case for self-serve documentation or product fixes.

Revenue by Product

Identify which products or SKUs generate the majority of revenue. Useful for portfolio reviews and resource allocation decisions.

Bug Prioritization

Rank bug categories by frequency or user impact. Focus engineering effort where it eliminates the most pain.

Cost Reduction

Show which expense categories account for the bulk of spend. Pareto charts make it obvious where cutting has the most effect.

Pareto Chart vs Bar Chart: What is the Difference?

Both use bars, but they answer different questions.

Pareto Chart

Best for: Prioritization, identifying the few causes that account for most of an effect.

Strength: The cumulative line makes the 80/20 threshold visible at a glance. Audiences immediately see where to focus.

Use when: Quality reviews, retrospectives, defect analysis, support triage, cost reduction.

Bar Chart

Best for: Comparison, showing how categories differ in magnitude without implying a priority order.

Strength: Simpler and more familiar. Works for any categorical comparison where rank order is not the main message.

Use when: Revenue by region, performance by team, product comparison, survey results.

AECharts supports both. Use a bar chart when you are comparing. Use a Pareto chart when you are prioritizing.
