在 highcharts 中，当我使用 addpoint() 添加数据时，允许 'shift' 为 'true' ，当数据量大时，工具提示不会移动，就像数据量少时工具提示一样。可以通过改变rangeSelector的范围来识别数据量。有什么我可以修改的或者我应该包含一些额外的代码吗？我已在下面的链接中重现了该问题。

// Create the chart
Highcharts.stockChart('container', {
chart: {
events: {
load: function () {
// set up the updating of the chart each second
var series1 = this.series[0];
setInterval(function () {
var x = (new Date()).getTime(), // current time
y = Math.round(Math.random() * 100);
series1.addPoint([x, y], true, true);
}, 2000);
var series2 = this.series[1];
setInterval(function () {
var x = (new Date()).getTime(), // current time
y = Math.round(Math.random() * 50);
series2.addPoint([x, y], true, true);

<div id="container" style="height: 400px; min-width: 310px"></div>预期结果:当鼠标指针悬停在任何标记上并保持原样时，工具提示应在新数据到达时移到后面。目前，当范围选择器数据较少时工作正常，但当数据较多时则不行。
最佳答案
该问题是由修改数据的 dataGrouping 属性引起的。您可以通过以下方式禁用它:
plotOptions: {
series: {
dataGrouping: {
enabled: false
},
...
}
}

关于javascript - 在 Highcharts 中，当图表具有高数据时，工具提示不会移动，这与图表具有低数据时不同，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/56343200/
