Pie Of A Pie Chart Excel

Pie of a Pie Chart Excel: A Complete Guide to Creating and Customizing This Useful Visualization

When you need to show how a small slice of a pie chart dominates the data while still revealing the details of that slice, Excel’s pie of a pie chart is the perfect tool. This chart type combines a primary pie that displays the big‑picture categories with a secondary, smaller pie that breaks down the selected slice into its sub‑components. It is especially helpful for highlighting “other” categories, top‑selling products, or any situation where a few items represent a large proportion of the total but you still want to see what makes them up.

Below is a step‑by‑step, SEO‑friendly walkthrough that covers everything from the concept behind a pie of a pie chart to advanced formatting tips, common pitfalls, and frequently asked questions. By the end, you’ll be able to create a clean, professional‑looking chart that tells a clear story with your data.

What Is a Pie of a Pie Chart?

A pie of a pie chart (sometimes written as “pie‑of‑pie”) is a hybrid chart that consists of two linked pies:

1. Main pie – shows all categories, but one or more slices are aggregated into a single “Other” slice (or a user‑defined slice).
2. Secondary pie – zooms in on the aggregated slice, displaying its individual components in detail.

This design solves a common problem: when a few categories dominate the data, the remaining slices become too small to read or compare effectively. By pulling those dominant slices out into a secondary pie, you keep the main chart readable while still providing the granularity needed for analysis.

Key benefits

• Improves readability of crowded pie charts.
• Highlights the contribution of specific sub‑categories within a dominant group.
• Keeps the visual footprint compact, ideal for dashboards and reports.

When to Use a Pie of a Pie Chart in Excel

Consider using this chart type when:

• One or two categories make up >60 % of the total and the rest are fragmented.
• You need to show the internal breakdown of a dominant slice without cluttering the main view.
• The audience is familiar with pie charts but would struggle to interpret tiny slices.
• You are building an executive summary where space is limited but insight is required.

Typical business examples include sales by product line (highlighting the top‑selling product), expense breakdowns (spotlighting the largest cost center), or market share analysis (focusing on the leading competitor).

Step‑by‑Step: How to Create a Pie of a Pie Chart in Excel

Follow these instructions to build your chart from scratch. The steps apply to Excel 2016 and later (including Excel for Microsoft 365).

1. Prepare Your Data

• Arrange your data in two adjacent columns: Category (text) and Value (numeric).
• Ensure there are no blank rows or columns within the range.

2. Insert the Chart

1. Highlight the entire data range (including headers).
2. Go to the Insert tab on the Ribbon.
3. In the Charts group, click the Pie icon.
4. From the dropdown menu, select Pie of Pie (or Bar of Pie if you prefer a bar sub‑chart).
5. Excel will automatically generate a pie of a pie chart using its default settings.

3. Choose Which Slice to Explode

By default, Excel selects the smallest values for the secondary pie. To change this:

1. Click on the chart to activate the Chart Tools (Design & Format tabs).
2. Right‑click the secondary pie (the smaller one) and choose Format Data Series.
3. In the Series Options pane, adjust:
   • Split Series By – choose Position, Value, Percentage Value, or Custom.
   • If you pick Custom, you can manually drag categories between the main and secondary pies using the chart legend or the data series editor.

Example: To highlight “Product A” and “Product B” in the secondary pie, set Split Series By to Custom, then drag those two items from the main pie to the secondary pie Simple as that..

4. Adjust the Size of the Secondary Pie

You can control how large the secondary pie appears relative to the main pie:

1. With the chart selected, go to Format Data Series → Series Options.
2. Use the Second Plot Size slider (values from 0 % to 100 %).
   • A larger percentage makes the secondary pie bigger, which is useful when you have many sub‑categories to display.
   • A smaller percentage keeps the focus on the main pie.

5. Add Data Labels and Formatting

Clear labeling helps readers interpret the chart quickly.

1. Click the chart, then choose Chart Elements (+ button) → Data Labels.
2. For more control, right‑click a data label → Format Data Labels.
   • Choose Value, Percentage, or Category Name as needed.
   • Adjust font size, color, and position (Inside End, Outside End, Best Fit).
3. Apply a chart style or color palette from the Design tab to match your corporate branding.
4. Remove unnecessary elements (e.g., legend if the labels are self‑explanatory) to reduce clutter.

6. Final Touches

• Title: Click the default chart title and type a descriptive name, e.g., “Sales Breakdown – Top Products vs. Others”.
• Resize: Drag the chart edges to fit your worksheet or dashboard layout.
• Copy as Picture: If you need to embed the chart in a PowerPoint slide, right‑click the chart → Copy → Paste Special → Picture (Enhanced Metafile).

Customizing Your Pie of a Pie Chart: Advanced Tips

Once the basic chart is in place, you can refine it further to suit specific analytical needs.

Changing the Split Method

• By Value: Ideal when you want to isolate categories above a certain threshold (e.g., all products selling >50 units).
• By Percentage Value: Useful for relative comparisons (e.g., show categories that together make up the top 30 %).
• By Position: Keeps the original order of your data; handy when the sequence matters (e.g., timeline‑based categories).

Using a Bar of Pie Instead

If the secondary pie feels too cramped, switch to a Bar of Pie:

1. Select the chart → Change Chart Type (right‑

Below, you’ll see how to complete the change‑type operation and lock in the final look of your dual‑pie visualization.

Changing the Split Method

After switching to a Bar of Pie, verify that the split logic still aligns with your story. The three options appear in the Format → Chart Style pane under Split Series by. Re‑apply any that were previously used:

A quick way to test each option is to use the Data toolbar’s “Swap Horizontal Positions” dialog: select a few slices, click Swap, and watch the re‑ordering instantly—this confirms the chosen method before committing.

Refining the Look

1. Color Consistency – Create a custom color scheme that mirrors your corporate palette. In the Design tab, click Customize Color Scheme and either upload a .acr file or define primary/secondary colors for “Main”, “Secondary”, and “Outer”. Applying the same scheme to both pies guarantees cohesion across the dashboard.

2. Label Styling – Keep numbers concise. Right‑click any label → Format Data Labels → General → uncheck Show Value if percentages already convey the information. Then choose a clean sans‑serif font (e.g., Calibri 9 pt), set the color to white against dark backgrounds, and move them to Inside End for optimal readability Nothing fancy..

3. Glass‑Morphism Effect (optional) – If your platform supports it, enable Shadow on one layer and add a subtle Transparency (≈ 10 %) to the outer pie. This gives a modern, layered feel without sacrificing clarity Most people skip this — try not to. Less friction, more output..

4. Interactive Filtering – Attach the chart to a slicer or dropdown that filters the underlying data range. When users toggle a category, the second pie automatically updates its split, letting viewers explore subsets dynamically.

Deploying the Chart

• Export for Reporting – Use File → Export As → PNG or PDF for static reports.
• Dashboard Integration – Insert the chart via Insert → Charts → From Existing Worksheet, linking it directly to the source table so future refreshes update the visual automatically.

Conclusion

By mastering the split‑series settings, adjusting plot sizes, adding clear labels, and fine‑tuning colors and interactivity, you transform a simple stacked pie into a powerful, narrative‑driven visual that highlights product performance at a glance. Day to day, whether you prioritize the raw volume of high‑selling items or the relative contribution of every segment, these steps give you full control over how the secondary pie behaves and what story it tells. Implement the advanced refinements outlined here, and your dual‑pie charts will stand out as polished, professional assets ready for any business presentation or analytics dashboard Easy to understand, harder to ignore..

No fluff here — just what actually works.
