React Native Chart Kit
React Native Chart Kit is a library that provides customizable and flexible charting components for React Native applications. It offers a wide range of chart types, including line charts, bar charts, pie charts, and others, that can be easily integrated into your React Native app.
One of the key benefits of using React Native Chart Kit is that it is highly customizable, with options to change colors, labels, axes, and more. You can also add interactive features such as tooltips and zooming to enhance the user experience.
React Native Chart Kit is also lightweight, making it easy to integrate into your app without slowing it down. The library uses native components, so charts are rendered smoothly and efficiently on iOS and Android.
Another advantage of using React Native Chart Kit is that it is well documented and has a large community of users, making it easy to find help and support when needed. Whether you are new to charting or an experienced data visualization expert, you can find the resources and support you need to create stunning charts in your React Native app.
To get started with React Native Chart Kit, simply install the library and import the components you need into your app. You can then pass data to the components and use the available props and methods to customize the charts to meet your specific needs as shown below :
Installation :
1. First, you need to install the package using this command:
- npm install react-native-chart-kit
2. Then use the ES6 syntax to import the components :
import {
LineChart,
BarChart,
PieChart,
ProgressChart,
ContributionGraph,
StackedBarChart
} from "react-native-chart-kit";
3. Then define a chart-style object with the following properties :
const chartConfig = {
backgroundGradientFrom: "#1E2923",
backgroundGradientFromOpacity: 0,
backgroundGradientTo: "#08130D",
backgroundGradientToOpacity: 0.5,
color: (opacity = 1) => `rgba(26, 255, 146, ${opacity})`,
strokeWidth: 2, // optional, default 3
barPercentage: 0.5,
useShadowColorFromDataset: false // optional
};
4. Quick example of Bar-chart:
const data = {
labels: ["January", "February", "March", "April", "May", "June"],
datasets: [
{
data: [20, 45, 28, 80, 99, 43]
}
]
};
<BarChart
style={graphStyle}
data={data}
width={screenWidth}
height={220}
yAxisLabel="$"
chartConfig={chartConfig}
verticalLabelRotation={30}
/>
5. Quick example of Pie-chart:
const data = [
{
name: "Seoul",
population: 21500000,
color: "rgba(131, 167, 234, 1)",
legendFontColor: "#7F7F7F",
legendFontSize: 15
},
{
name: "Toronto",
population: 2800000,
color: "#F00",
legendFontColor: "#7F7F7F",
legendFontSize: 15
},
{
name: "Beijing",
population: 527612,
color: "red",
legendFontColor: "#7F7F7F",
legendFontSize: 15
},
{
name: "New York",
population: 8538000,
color: "#ffffff",
legendFontColor: "#7F7F7F",
legendFontSize: 15
},
{
name: "Moscow",
population: 11920000,
color: "rgb(0, 0, 255)",
legendFontColor: "#7F7F7F",
legendFontSize: 15
}
];
<PieChart
data={data}
width={screenWidth}
height={220}
chartConfig={chartConfig}
accessor={"population"}
backgroundColor={"transparent"}
paddingLeft={"15"}
center={[10, 50]}
absolute
/>
