fetch('https://www.alphavantage.co/query?function=TIME_SERIES_DAILY&symbol=IBM&apikey=demo')
.then(res => res.json())
.then(data => {
const cdata = data.map(d => {
{time:d[0],open:[1],high[2],low[3],close[4]}
});
candleSeries.setData(cdata);
})
.catch(err => log(err))
When I run this code, there have an error like data.map is not function
Maybe you should Add Return before {time:d[0],open:[1],high[2],low[3],close[4]}
It's Like this return {time:d[0],open:[1],high[2],low[3],close[4]}
