react-native-gifted-charts 
The most complete library for Bar, Line, Area, Pie, Donut and Stacked Bar charts in React Native. Allows 2D, 3D, gradient, animations and live data updates.
Yet another chart library? Why?
To bring Life to your data
- Plenty of features with minimal code
- Apply animations to your charts on load and on value change, just by adding a prop
- Smooth animations implemented using LayoutAnimation
- Clickable and scrollable
- Three-D and gradient effects
- Fully customizable (see the props)
- Detailed documentation with examples
- Support for combined Bar and Line charts
Alert:
This library doesn't support web apps yet. Use this library if you are planning mobile first.
However, we are planning to add support for web which will be available soon.

Version 1.2.x 🎉
Version 1.2.0 onwards we are dependent only on react-native-svg and react-native-linear-gradient. Earlier, Pie and Donut charts were rendered using react-native-canvas, but now they are also rendered using svg. We are no longer using react-native-canvas neither react-native-webview!
Installation
npm install react-native-gifted-charts react-native-linear-gradient react-native-svg
For iOS-
cd ios && pod install
Docs
Usage
The simplest usage of various types of charts can be done as below-
import { BarChart, LineChart, PieChart } from "react-native-gifted-charts";
// ...
const data=[ {value:50}, {value:80}, {value:90}, {value:70} ]
<BarChart data = {data} />
<LineChart data = {data} />
<PieChart data = {data} />
// For Horizontal Bar chart, just add the prop horizontal to the <BarChart/> component
<BarChart data = {data} horizontal />
// For Area chart, just add the prop areaChart to the <LineChart/> component
<LineChart data = {data} areaChart />
// For Donut chart, just add the prop donut to the <PieChart/> component
<PieChart data = {data} donut />
Props tables
1. BarChart, Horizontal BarChart and Stacked Bar Chart props
2. LineChart and AreaChart props
3. PieChart and DonutChart props

Common issues
| Issue | Solution |
|---|---|
| BarChart - Value and section line don't match | Comment by the owner |
Setting height, maxValue, stepValue, stepHeight, or noOfSections breaks the chart |
Please make sure thatmaxValue = noOfSections * stepValue; is followed. See this |
| Charts with datasets having negative values (4th quadrant) break https://github.com/Abhinandan-Kushwaha/react-native-gifted-charts/issues/261 | Not yest solved |
