Question 1

How do I add pinch-to-zoom to a Flutter chart?

Accepted Answer

Bezier Chart has built-in pinch-to-zoom for date-based scales; enable it by setting pinchZoom to true in the config, allowing users to switch between weekly, monthly, and yearly views seamlessly.

Question 2

Bezier Chart vs fl_chart for interactive line charts?

Accepted Answer

Bezier Chart focuses on bezier-curve aesthetics and smooth animations, ideal for visually engaging dashboards. fl_chart offers more chart types like bar and pie, but may lack the same level of bezier customization.

Question 3

Can Bezier Chart handle DateTime data for time-series?

Accepted Answer

Yes, it natively supports DateTime objects with scales like WEEKLY, MONTHLY, and YEARLY, and includes an onMissingValue callback to fill gaps in time-series data.

Question 4

How to customize the bubble indicator in Bezier Chart?

Accepted Answer

Use properties like bubbleIndicatorColor, bubbleIndicatorTitleStyle, and bubbleIndicatorValueFormat in BezierChartConfig to adjust colors, text styles, and number formats for the interactive indicator.

Question 5

Is Bezier Chart good for real-time data updates?

Accepted Answer

It can handle dynamic updates by modifying the series data, but performance may suffer with very frequent changes due to bezier recalculations and animations, so test with your dataset size.

Question 6

What are the alternatives to Bezier Chart in Flutter?

Accepted Answer

For more chart types, consider fl_chart or syncfusion_flutter_charts. If you need simpler, static charts, charts_flutter might suffice, but they lack bezier smoothness and rich interactivity.
