line chart must update all 10,000 points every second
Your code is actually adding points instead of updating (replacing) them, so memory runs out. Try this :
setInterval(function () {
newdata = generateData(dataCount);
opt = myChart.getOption();
opt.xAxis= {data: newdata.categoryData };
opt.series[0].data= newdata.valueData;
myChart.setOption(opt, true); // replace
}, 1000);
I've actually tried this configuration and it still leads to memory building albeit more slowly
A work around that we found was to simply disable sampling and it works as expect
I'll try to create a repro, but +1 to this issue. At scale, using sampling: 'lttb'
can crash the browser when there are thousands of series and we also ended up disabling it
I have met the same problem, it looks like echarts' sampling issue.
