TreeMap Chart

A Treemap visualizes hierarchical data as a set of nested rectangles, where the size and color of each rectangle represent its value and sub-group.

A TreeMap Chart is a visualization designed to display large volumes of classified or hierarchical data in a compact space. It organizes data into nested rectangles, where the size of each rectangle represents the magnitude of a quantitative variable, and the color (or gradient) highlights additional dimensions or comparisons. TreeMaps make it easy to identify patterns, proportions, and outliers within hierarchical structures, offering a quick way to explore data density and relationships.

Best use case:

• To view all hierarchical data at once, enabling high-level comparisons while still showing granular details.

Examples:

• Visualizing company revenue by department → team → product line.

• Displaying website traffic by channel → campaign → source.

• Analyzing portfolio allocation by sector → industry → company.

Variations:

• Color-Coded Rectangles – Each rectangle can be colored differently to highlight the hierarchical structure.

• Gradient Fill – Rectangles can use gradients to reflect value ranges.

When to Use a TreeMap Chart

Use a TreeMap Chart when you need to:

• Display hierarchical data structures in a single visualization.

• Compare proportions between categories and subcategories.

• Spot patterns, clusters, or anomalies quickly using size and color.

• Replace or complement a Pie Chart or Bar Chart when the number of categories is too high for clarity.

• Summarize data for executive dashboards where space is limited but detail and proportions matter.

Chart Properties

The TreeMap Chart Properties allow you to configure ordering, data labels, color gradients, axis formatting, and insights to make hierarchical data visualizations more effective.

General Settings

• Order – Choose how TreeMap sections are displayed:

  • None – Default order.

  • Ascending – Sort values in increasing order.

  • Descending – Sort values in decreasing order.

  • Manual Sort – Manually reorder dimensions using sort indicators.

If Ascending or Descending is selected:

• Order By – Select the field (dimension or measure) used for ordering.

• Limit – Define the maximum number of items displayed.

• Exclude Global Filter – Exclude this TreeMap from any report-level filters.

• Show Data Label – Display category names or values directly on the chart.

• Gradient – Apply gradient coloring to improve visual differentiation:

  • Enabled – Choose Start Color and End Color to apply gradient shading.

  • Disabled – Select a fixed Color for each section.

View Filter

• Filter – Apply conditions to limit chart data (e.g., Source = Internal).

Note: View filters are reflected once the chart is added to the final report.

Axis

• Format Type – Choose how numbers are displayed:

  • None, Auto, Percent, Thousand, Lacs, Crore, Million, Billion, Trillion, Quadrillion.

• Currency Type – Add a currency symbol to values:

  • None, Rupees, Euro, Pound, USD, Yen, Cent.

• Precision – Set decimal places (up to 5).

Example: Show the Sum of Experience grouped by Team, formatted in Thousands with 2 decimals.

Insights

Use the Insights section to annotate the chart and highlight findings.

• Text – Add annotation text. Highlight values using asterisks (e.g., 70%, Top Performer).

• Font Size – Adjust text size.

• Font Color – Select a font color for the annotation.

• Text Align – Left, Right, or Centre.

• Position – Bottom or Right placement on the chart.
