Implementing Funnel Charts in .NET MAUI

A comprehensive skill for implementing and customizing Syncfusion .NET MAUI Funnel Charts (SfFunnelChart). Funnel charts visualize data as progressively decreasing segments, ideal for representing stages in a process like sales pipelines, conversion funnels, or marketing campaigns.

When to Use This Skill

Use this skill when you need to:

• Create funnel charts to visualize process stages (sales, marketing, conversion)
• Display hierarchical data with progressively narrowing segments
• Show conversion rates or drop-off analysis
• Implement customizable funnel visualizations with data labels and legends
• Export funnel charts as images

Component Overview

SfFunnelChart is a .NET MAUI control that creates beautiful funnel segments to analyze various stages in a process. Key capabilities include:

• User Interaction: Selection, tooltips, and legend toggling
• Data Labels: Display values with customizable placement and styling
• Legend Support: Scrollable legends with item identification
• Customization: Appearance, colors, gradients, spacing, and effects
• Orientation: Vertical or horizontal funnel display
