The DevExpress WinForms TreeMap (TreeMapControl) allows you to integrate area-based data visualizion for complex hierarchical data structures into your application. A treemap visualization consists of nested rectangles. The sizes of the rectangles are proportional to the corresponding data value.

Getting Started

• Lesson 1 - Create a Simple Unbound TreeMap
• Lesson 2 - Bind a TreeMap to Flat Data

Bind to Data

You can bind the TreeMap control to flat and hierarchical data structures, or create a treemap visualization manually (the unbound mode). Read the following topics for details and examples:

• Bind a TreeMap to Data
• How to: Bind a TreeMap to Hierarchical Data
• How to: Bind a TreeMap to Flat Data
• How to: Manually Add Items to a TreeMap

Layout Algorithms

You can use one of the following pre-built item-arrangement algorithms or implement a custom algorithm.

• Strip
• Squarified
• Slice and Dice
• Custom Algorithm

TreeMap Colorizers

TreeMap colorizers automatically specify colors for tree map items. You can use the following pre-built color distribution algorithms or implement a custom algorithm.

Palette Colorizer

Gradient Colorizer

Group Gradient Colorizer

Range Colorizer

Run Demo

Selection and Tooltips

The TreeMap control supports interactive highlighting, selection, and helper hints (tooltips).
