Implementing .NET MAUI Pyramid Charts

Guide users to implement Syncfusion .NET MAUI Pyramid Chart (SfPyramidChart), which visualizes proportions of a total in hierarchical segments, making it ideal for displaying parts-to-whole relationships in high-quality .NET MAUI applications. As a single-series chart without axes, data is represented as percentages where the sum of parts equals the whole.

When to Use This Skill

Use this skill when the user needs to:

• Create pyramid charts to visualize hierarchical or proportional data in .NET MAUI applications
• Display parts-to-whole relationships where segments represent percentages of a total
• Implement funnel-like visualizations for sales stages, process flows, or demographic breakdowns
• Add interactive features like tooltips, legends, and data labels to pyramid charts
• Customize appearance with palettes, gradients, and segment spacing
• Export chart visualizations as images (JPEG/PNG) or streams for reports and documents
• Configure data binding from view models to pyramid chart segments

Component Overview

The SfPyramidChart control provides:

• Single-series hierarchical data visualization
• Interactive tooltips and legends with customization
• Rich data label placement options (Auto, Inner, Center, Outer)
• Custom palette brushes and gradient support
• Two pyramid modes: Linear (height-based) and Surface (area-based)
• Segment spacing control with GapRatio
• Export to image formats or streams
• Toggle series visibility through legend interaction
• Scrollable legends for overflow handling
