ReactNative Chart Integration

React Native Chart

React Native provides several libraries that make it easy to integrate chart functionality into your mobile applications. One popular library for this purpose is react-native-chart-kit. It supports various chart types, including line charts, bar charts, pie charts, and more.

Below is a simple example of how to use react-native-chart-kit to create a line chart.

Step 1: Install the library

npm install react-native-chart-kit

Step 2: Import the library and create a LineChart

import React from 'react';
import { View, Text } from 'react-native';
import { LineChart } from 'react-native-chart-kit';

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

  return (
    <View>
      <Text>Line Chart Example</Text>
      <LineChart
        data={data}
        width={300} // from react-native
        height={200}
        yAxisLabel="$"
        yAxisSuffix="k"
        yAxisInterval={1}
        chartConfig={{
          backgroundColor: '#e26a00',
          backgroundGradientFrom: '#fb8c00',
          backgroundGradientTo: '#ffa726',
          decimalPlaces: 2,
          color: (opacity = 1) => `rgba(255, 255, 255, ${opacity})`,
          labelColor: (opacity = 1) => `rgba(255, 255, 255, ${opacity})`,
          style: {
            borderRadius: 16,
          },
          propsForDots: {
            r: '6',
            strokeWidth: '2',
            stroke: '#ffa726',
          },
        }}
        bezier
        style={{
          marginVertical: 8,
          borderRadius: 16,
        }}
      />
    </View>
  );
};

export default ChartExample;

This example shows a simple line chart with hardcoded data. You can customize the chart appearance using the chartConfig prop. Refer to the react-native-chart-kit documentation for more customization options and information on other types of charts.
