React Native Animated Charts
React Native Animated Charts is a user interface component library for building interactive line graphs and data visualizations within mobile applications. It functions as a cross-platform component for rendering scalable vector graphics chart paths, touch-following indicators, and dynamic axis labels on iOS and Android devices.
The library incorporates data processing capabilities to prepare raw datasets for display. It handles cubic spline data smoothing to transform coordinate sets into continuous curves, alongside downsampling algorithms to reduce point density while retaining critical extremes and endpoints. Visual transitions between datasets are managed through native animation execution across the bridge.
Interaction features include gesture-driven touch tracking that allows users to inspect precise data points using tracking dots, vertical lines, and haptic feedback. It also includes value-to-label formatting functions to convert raw numeric coordinates into readable strings such as currency or timestamps for axis display.
