what is the error?
what is the error?
The chart doesn't show up although there isn't any error. I just wonder if there is anyone has used this library with the typescript template which is created by Expo CLI? or it doesn't work because it doesn't support typescript so we can close this issue.
Can you inspect the webview? maybe there is an error there.
Sorry, I can't inspect the webview, I've only tested it on a real device which is connected with Expo.

Had tough time using the package. So went about custom approach using WebView.

I'm new here can you make a demo. That will be great. 👍
I know this library is deprecated but hope someone has also met the issue. I tried following the instruction but it doesn't work.
My steps:
const Chart: React.FC = () => { const [chartOptions, setChartOptions] = useState();
useEffect(() => { let intervalId: NodeJS.Timer; const chartOptionsTest = { chart: { events: { load: function () { // @ts-ignore // set up the updating of the chart each second const series = this.series[0]; intervalId = setInterval(function () { const y = Math.random(); series.addPoint(y, true, true); }, 1000); } } }, series: [{ data: [1, 2, 3] }] } setChartOptions(chartOptionsTest);
}, [])
return (
) }
const styles = StyleSheet.create({ container: { backgroundColor: '#fff', justifyContent: 'center', flex: 1 } });
export default Chart;
