I'm working on a react native application where I want to show data in the chart and then export the chart to PNG or Base64 image.
I'm using react-native-charts-wrapper library where I'm able to show the data in charts but not in able to convert it to base64 or png.
below is my code:



export default class App extends React.Component {

constructor() {
super();

this.state = {
legend: {
enabled: true,
textSize: 14,
form: 'SQUARE',
formSize: 14,
xEntrySpace: 10,
yEntrySpace: 5,
formToTextSpace: 5,
wordWrapEnabled: true,
maxSizePercent: 0.5
},
data: {
dataSets: [{
values: [{y: 100}, {y: 105}, {y: 102}, {y: 110}, {y: 114}, {y:
109}, {y: 105}, {y: 99}, {y: 120}],
label: 'Bar dataSet',
config: {
color: processColor('pink'),
drawBarShadow: true,
barShadowColor: processColor('red'),
highlightAlpha: 90,
highlightColor: processColor('red'),
}
}],

config: {
barWidth: 0.7,
}
},
highlights: [{x: 3}, {x: 6}],
xAxis: {
valueFormatter: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'oct'],
granularityEnabled: true,
position: 'BOTTOM',
granularity : 1,
},
yAxis: {
left:{axisMinimum: 10}}
};
}

handleSelect(event) {
let entry = event.nativeEvent
if (entry == null) {

this.setState({...this.state, selectedEntry: null})
} else {
this.setState({...this.state, selectedEntry: JSON.stringify(entry)})
}

console.log(event.nativeEvent)
}


render() {
return (
<View style={{flex: 1}}>

<View style={{height:80}}>
<Text> selected entry</Text>
<Text> {this.state.selectedEntry}</Text>
</View>


<View style={styles.container}>
<BarChart
style={styles.chart}
data={this.state.data}
xAxis={this.state.xAxis}
animation={{durationX: 2000}}
legend={this.state.legend}
gridBackgroundColor={processColor('#000000')}
visibleRange={{x: { min: 5, max: 5 }}}
drawBarShadow={false}
drawValueAboveBar={true}
drawHighlightArrow={true}
onSelect={this.handleSelect.bind(this)}
highlights={this.state.highlights}
onChange={(event) => console.log(event.nativeEvent)}
/>
</View>
</View>
);
}
}


Is there any other library for the requirement or react-native-charts-wrapper inbuilt have any method to export it in base64.

  • @Asha Thanks for the quick response but my chart is scrollable so if I take the screenshot it will not full and always be the visible chart on the screen.

  • @Asha I tried the above solution but my chart is not inside scrollview and its Barchart is itself scrollable as there are large data on x-axis and it's only capturing the bars available on the screen, not the remaining bars which are visible only on scrolling.
