react-native-gifted-charts

       

The most complete library for Bar, Line, Area, Pie, Donut, Stacked Bar and Population Pyramid charts in React Native. Allows 2D, 3D, gradient, animations and live data updates.

Yet another chart library? Why?

To bring Life to your data

1. Plenty of features with minimal code
2. Apply animations to your charts on load and on value change, just by adding a prop
3. Smooth animations implemented using LayoutAnimation
4. Clickable and scrollable
5. Three-D and gradient effects
6. Fully customizable (see the props)
7. Detailed documentation with examples
8. Support for combined Bar and Line charts
9. Tested to be pixel perfect using react-native-screenshot-test. See the screenshot tests here

The web counterpart of this library is public now. Try out our new reactJS library- react-gifted-charts
The exact same piece of code that you write to render charts in react-native, can be used to render charts in reactJS using this library!
