TypeError: performance.now is not a function when using lightweight chart
See original GitHub issueLightweight Charts Version: 3.7.0
Steps/code to reproduce: I import the script like this
<script src="https://unpkg.com/lightweight-charts/dist/lightweight-charts.standalone.production.js"></script>
I get the data set from Google cloud firestore as the input
<script type="text/javascript">
$(document).ready(function() {
db.collection('爬蟲歷史資料').doc("費半").collection("歷史價錢").get().then((documents) => {
var histData = []
documents.forEach(function(doc) {
var json = {
'time': doc.id,
'value': parseFloat(doc.data().price.toString().replace(",", ""))
}
histData.push(json);
})
console.log(histData)
// 建立技術分析圖
var width = document.getElementById("stock-chart").getBoundingClientRect().width * 1.05;
var height;
if (screen.width <= 1920) {
height = 500;
} else if (screen.width <= 3840) {
height = 1120;
}
var dest = document.getElementById("SOX");
var chart = LightweightCharts.createChart(dest, {
width: width,
height: height,
layout: {
textColor: '#d1d4dc',
backgroundColor: 'rgba(0, 0, 5, 0.9)',
},
rightPriceScale: {
scaleMargins: {
top: 0.3,
bottom: 0.25,
},
},
crosshair: {
vertLine: {
width: 5,
color: 'rgba(224, 227, 235, 0.1)',
style: 0,
},
horzLine: {
visible: false,
labelVisible: false,
},
},
grid: {
vertLines: {
color: 'rgba(42, 46, 57, 0.8)',
},
horzLines: {
color: 'rgba(42, 46, 57, 0.8)',
},
},
});
var areaSeries = chart.addAreaSeries({
topColor: 'rgba(38, 198, 218, 0)',
bottomColor: 'rgba(38, 198, 218, 0)',
lineColor: 'rgba(51, 51, 255, 1)',
lineWidth: 2,
crossHairMarkerVisible: false,
});
console.log("set data")
areaSeries.setData(histData);
dest.style.position = 'relative';
var legend = document.createElement('div');
legend.classList.add('legend');
dest.appendChild(legend);
var firstRow = document.createElement('div');
firstRow.innerText = '費半';
firstRow.style.color = 'white';
firstRow.style.fontFamily = 'Microsoft JhengHei';
legend.appendChild(firstRow);
function pad(n) {
var s = ('0' + n);
return s.substr(s.length - 2);
}
chart.subscribeCrosshairMove((param) => {
if (param.time) {
const price = param.seriesPrices.get(areaSeries);
const date = param.time['year'] + "/" + param.time['month'] + "/" + param.time['day']
firstRow.innerText = '費半' + ' ' + date + ' ' + parseFloat(price).toFixed(2);
} else {
firstRow.innerText = '費半';
}
});
});
});
</script>
Actual behavior:
An error occur when calling var areaSeries = chart.addAreaSeries
and the chart only shows background.
Expected behavior:
Originally, it will shows a chart with my own data on it.
Screenshots: Error message
Chart with only background

I just stopped on the exception and look at the code caused it. You can enable this option in your devtools so you’ll stop on every uncaught exception too so you’ll see call stack, local and global variables at the time.
Thanks a lot! I didn’t notice that. How did you find out? You’re very professional!
