102};This React example demonstrates how to integrate a Polar Band Chart using SciChart's React components. The chart displays two polar band series with different interpolation modes in a polar coordinate system.
The chart is rendered using the SciChartReact component with an initChart prop pointing to the drawExample function. This function creates a polar surface with radial and angular axes, then adds two PolarBandRenderableSeries instances with SweepAnimation for smooth transitions. The implementation uses React's component lifecycle for proper initialization and cleanup.
The example highlights React-specific integration of polar chart features including animated series, interactive modifiers (PolarMouseWheelZoomModifier, PolarZoomExtentsModifier), and a configurable legend. The component demonstrates how to apply theme colors from a shared appTheme object.
The implementation shows best practices for using SciChart in React, including async initialization and proper component structure. For more on React integration, see the SciChart React documentation.
