How to Create a Treemap Chart in Excel?

In this article, you will learn how to create a Treemap Chart in Excel, a dynamic and visually compelling tool for representing hierarchical data through nested rectangles. A Treemap Chart displays data in a hierarchical structure, where each branch of the hierarchy is represented by a colored rectangle. The size of each rectangle corresponds to a specific data metric, providing an immediate visual understanding of the distribution and proportions within the dataset.

Excel’s intuitive interface makes it easy to generate Treemap Charts, enabling you to effectively communicate complex hierarchical relationships and identify patterns within your data. Follow our guide on how to create a Treemap in Excel to harness this powerful charting feature and present your hierarchical data in an engaging and informative way.

How to Create a Treemap Chart in Excel?

Here are the step-by-step instructions on how to create a Treemap Chart in Excel:

  1. Open Your Excel Spreadsheet: Launch Microsoft Excel and open the spreadsheet containing the hierarchical data you want to visualize.
  2. Organize Your Data: Ensure your data is structured hierarchically, with clear columns for categories and subcategories. The last column should represent the values or sizes you want to visualize.
  3. Select Your Data: Highlight the entire dataset, including category names, subcategories, and values. Make sure your data has clear headers.
  4. Go to the “Insert” Tab: Navigate to the “Insert” tab in the Excel ribbon at the top of the screen.
  5. Choose “Treemap Chart” Type: Within the “Charts” or “Chart Types” group, click on the “Treemap” option. Excel will automatically generate a Treemap Chart based on your selected data.
  6. Adjust the Treemap: After inserting the chart, Excel may automatically organize your data into a Treemap. However, you may need to make adjustments. Right-click on the chart, choose “Select Data,” and ensure your category and subcategory data are correctly recognized.
  7. Customize the Chart: Utilize the Chart Tools available in the ribbon to customize the appearance of your Treemap. This includes changing colors, titles, and labels to enhance the visual appeal and clarity of the chart.
  8. Format Data Labels: Enhance readability by adding data labels to the Treemap. Click on individual data rectangles, right-click, and choose “Add Data Labels” to display the values.
  9. Adjust Color Scales (Optional): If you want to emphasize certain aspects of your data, modify the color scale of the Treemap. Right-click on the chart, choose “Format Data Series,” and adjust the color settings.
  10. Expand or Collapse Hierarchies (Optional): Excel Treemaps often allow you to expand or collapse hierarchies for a more detailed or high-level view. Click on the “+” and “-” icons next to category names to adjust the level of detail.
  11. Save Your Workbook: Save your Excel workbook to preserve the changes made to the Treemap Chart.
  12. Update the Chart with New Data: If your hierarchical data changes, right-click on the chart and choose “Select Data.” Adjust the data range to update the Treemap Chart accordingly.
  13. Explore Advanced Chart Options: Depending on your needs, explore advanced options such as adjusting labels, adding borders, or other features available in the Chart Tools.
  14. Add Titles and Legends: Make your Treemap informative by including a title and legend. Titles convey the main message, while legends explain the categories represented in the Treemap.
  15. Format the Chart Area: Fine-tune the appearance of the chart area, including background colors and border, to align with your visual preferences.

By following these steps, you can create a Treemap Chart in Excel, offering a dynamic and visually impactful way to represent hierarchical data. Excel’s user-friendly charting tools provide flexibility for customization, allowing you to tailor your Treemap to suit your specific data visualization needs.
