Hi Dev,

In this blog,I will learn you how to use bar chart in react native. We will show example of bar chart in react native. You can easliy create react native bar chart. First i will import bar namespace from react-native-svg-charts, after I will make bar chart using in react native.

In the first step Run the following command for create project.

expo init MyWebtuts 

In the step, Run the following command for installation of dependency.

To use bar you need to install react-native-svg-chartss package.

To install this open the terminal and jump into your project

cd paper MyWebtuts 

yarn add react-native-svg-charts

yarn add d3-shape

yarn add react-native-paper

In this step, You will open App.js file and put the code.

import React, { Component } from "react";
import { View,StyleSheet,Text} from 'react-native';
import { Provider ,Appbar,Card} from 'react-native-paper';
import { BarChart ,Grid} from 'react-native-svg-charts';
import * as shape from 'd3-shape';

const MyWebtutsComponent = () => {
      
    const fill = 'rgb(0, 0, 50)'

    const data = [50, 10, 60, 105, -40, -25, null, 85, undefined, 0, 35, 53, -53, 24, 50, -20, -80]

    const _goBack = () => console.log('Went back');

    const _handleSearch = () => console.log('Searching');

    const _handleMore = () => console.log('Shown more');

    return (
      <Provider>
          <Appbar.Header style={styles.header}>
            <Appbar.BackAction onPress={_goBack} />
            <Appbar.Content title="MyWebtuts" subtitle="Subtitle" />
            <Appbar.Action icon="magnify" onPress={_handleSearch} />
            <Appbar.Action icon="dots-vertical" onPress={_handleMore} />
          </Appbar.Header>
          <View style={styles.mainbox}>
            <Text style={styles.title}>React Native Bar Chart Example</Text>
            <Card style={styles.cardbox}>
              <BarChart style={{ height: 250 }}  data={data} svg={{ fill }} contentInset={{ top: 30, bottom: 30 }}>
                <Grid />
              </BarChart>
             </Card>
          </View>
      </Provider>
    );
  };


const styles = StyleSheet.create({
    mainbox:{
      textAlign:'center',
      margin: 15,
      justifyContent: 'space-between',
    },
    title:{
      fontSize: 16
    },
    cardbox:{
      marginTop: 10,
      padding: 15,
    }
});
export default MyWebtutsComponent;

In the last step run your project using bellow command.
