Vertical Bar Graph

Installation

npm package

npm i @chartiful/react-native-chart-builder @chartiful/react-native-vertical-bar-graph

Example

import VerticalBarGraph from '@chartiful/react-native-vertical-bar-graph';
import { View, StyleSheet } from 'react-native';

const config = {
  hasXAxisBackgroundLines: false,
  xAxisLabelStyle: {
    position: 'right',
    prefix: '$'
  }
};

export const YourComponent = () => (
  <View>
    <VerticalBarGraph
      data={[20, 45, 28, 80, 99, 43, 50]}
      labels={['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul']}
      width={375}
      height={300}
      barRadius={5}
      barWidthPercentage={0.65}
      baseConfig={config}
      style={styles.chart}
    />
  </View>
);

const styles = StyleSheet.create({
  chart: {
    marginBottom: 30,
    padding: 10,
    paddingTop: 20,
    borderRadius: 20,
    backgroundColor: 'green',
    width: 375
  }
});
