This blog will guide you through creating a multi-layered pie chart in WPF using the Syncfusion Circular Chart control. We’ll build an interactive chart that not only visualizes vitamin and food source data but also dynamically displays detailed information using the Syncfusion Diagram control upon selection.
A Circular chart is a type of data visualization that displays information in a round format, often used to represent proportions, categories, or hierarchical relationships. Common examples include pie charts, and doughnut charts. These charts are especially effective for showing how parts contribute to a whole, making them popular in dashboards, reports, and nutrition visualizations.
The Syncfusion WPF Circular Chart is a powerful and flexible control that offers several advantages for creating sophisticated data visualizations:
- Multi-Level Visualization: Easily create multi-layered pie and doughnut charts to represent complex, hierarchical, or related data.
- Rich Interactivity: Comes with built-in support for selection, tooltips, and animations that enhance the user experience.
- High Performance: Optimized for smooth rendering and interaction, even with large datasets.
- Customization: Provides extensive options for customizing every aspect of the chart, from labels and colors to adornments and legends.
In this blog, we’ll explore how to visualize the relationship between various vitamin groups and their corresponding food sources using a multi-layered pie chart in WPF. Additionally, we’ll enhance the user experience by integrating the Syncfusion Diagram control to dynamically display detailed nutritional information upon selection.
Set up data models to represent the vitamins and their food sources structure. The chart will be structured as follows:
- The inner pie represents major vitamin groups (A, B, C, D, E).
- The outer pie shows specific food sources for all those vitamins.
- When a user clicks on a segment (either a vitamin or a food source), the chart highlights the selected vitamin group and its corresponding foods.
- Simultaneously, a Syncfusion Diagram control on the right updates to display the selected vitamin, its food sources, and their caloric information in a clear, hierarchical tree structure.
