FAQPage Schema

How do I create declarative charts in WinUI to reduce boilerplate?▼

Declarative charts in WinUI use a fluent DSL to define chart types, axes, and labels, reducing boilerplate between data and visuals. You configure LineChart, BarChart, AreaChart, PieChart, TreeChart, and ForceGraph directly through extension methods.

Can I add custom icons and multi-line content to WinUI chart labels?▼

Custom icons and multi-line content can be added to WinUI chart labels using *View extensions. These extensions allow you to build custom labels and visual elements beyond standard text, providing flexible data labeling directly on the chart.

How do I make data visualization accessible in a WinUI application?▼

Data visualization is made accessible by implementing the IChartAccessibilityData surface, which exposes chart data to assistive technologies. This built-in accessibility surface ensures dashboards and analytics pages meet accessibility requirements.

Does WinUI Reactor support force-directed graphs and tree charts?▼

WinUI Reactor supports both ForceGraph and TreeChart types alongside LineChart, BarChart, AreaChart, and PieChart. You declare these complex visualizations using the same fluent DSL and customize them with axes, palettes, and sizing options.

What is the best way to label data points versus using tooltips in WinUI charts?▼

Direct labeling is preferred for immediate readability, while tooltips and legends provide supplementary details. The chart DSL includes built-in direct labeling features and guidance on when to apply direct labels versus legends or tooltips for optimal data communication.

Are declarative charts suitable for building responsive dashboards in WinUI?▼

Declarative charts are suitable for responsive dashboards, analytics pages, and data-rich UIs. The fluent API allows customization of palettes and sizing, ensuring visuals remain accessible, responsive, and themeable across different display contexts.
