How to Display Data Labels for Specific Points in .NET MAUI Cartesian Chart

This sample demonstrates how to show data labels only for selected data points in a .NET MAUI SfCartesianChart using Syncfusion controls. This technique helps reduce visual clutter and improves readability, especially in charts with many data points.

What You'll Learn

• How to associate each data point with a ShowLabel property to control label visibility.
• How to apply business logic to determine which points should display labels.
• How to bind data to the chart and use a LabelTemplate for conditional label rendering.

Key Steps

1. Add a ShowLabel Property - Each data point includes a flag to indicate whether its label should be shown.

2. Apply Business Logic - Set ShowLabel based on conditions like value thresholds or specific indices.

3. Bind Data to Chart - Connect your data source to the chart and enable data labels.

4. Use a LabelTemplate - Customize label appearance and visibility using data binding.

Benefits

• Keeps the chart clean and focused.
• Adapts easily to different scenarios (e.g., highlight outliers).
• Ensures UI reflects business logic dynamically.
