Using Charts in React Native

Charts are an essential tool for displaying data in a visually appealing and understandable way. In React Native, there are several libraries that allow developers to integrate charts into their applications with ease. In this article, we will explore three of the most popular charting libraries for React Native and provide step-by-step instructions on how to use them.

React Native Chart Kit

React Native Chart Kit is a popular library for creating charts in React Native applications. It offers a range of chart types, including line, bar, pie, and progress, as well as customizable colors and animations. Here are the steps required to use React Native Chart Kit in your application: Installation

To install React Native Chart Kit, run the following command:

npm install react-native-chart-kit

Usage

After installing React Native Chart Kit, you can import the chart type you want to use and render it in your component. Here’s an example of how to render a line chart:

import { LineChart } from 'react-native-chart-kit';

const data = {
  labels: ['January', 'February', 'March', 'April', 'May', 'June'],
  datasets: [
    {
      data: [20, 45, 28, 80, 99, 43],
    },
  ],
};

const chartConfig = {
  backgroundGradientFrom: '#1E2923',
  backgroundGradientTo: '#08130D',
  color: (opacity = 1) => `rgba(26, 255, 146, ${opacity})`,
};

<LineChart data={data} width={screenWidth} height={220} chartConfig={chartConfig} />

This code renders a line chart with sample data and a custom color configuration.

Victory Native

Victory Native is another popular charting library for React Native. It offers a wide range of chart types, including area, bar, line, and pie charts, and supports complex data visualizations. Here’s how to use Victory Native in your application: Installation

const data = [
  { quarter: 1, earnings: 13000 },
  { quarter: 2, earnings: 16500 },
  { quarter: 3, earnings: 14250 },
  { quarter: 4, earnings: 19000 },
];

<VictoryBar data={data} x="quarter" y="earnings" />

This code renders a bar chart with sample data.

React Native SVG Charts
