How do I detect a zoom event in highcharts?
提问by Andrey
Is it possible to detect a zoom event in Highcharts? My use case is that I have some state external to the chart, and when the user zooms in on part of it I want to detect what the new time range on the x-axis is and update the corresponding external state.
是否可以在 Highcharts 中检测缩放事件？我的用例是我在图表外部有一些状态，当用户放大其中的一部分时，我想检测 x 轴上的新时间范围是什么并更新相应的外部状态。

Have you tried going through the Highcharts API?
你试过通过Highcharts API吗？
You may want to look @ xAxis.events.setExtremesAnd/Or chart.events.selection
你可能想看看@ xAxis.events.setExtremes和/或 chart.events.selection

You want to look at the redraw event as well. When you zoom, the chart is redrawn to reflect the changes. chart.events.redraw
您还想查看重绘事件。缩放时，图表会重新绘制以反映更改。chart.events.redraw
events: {
redraw: function(){
console.log(this.xAxis);
console.log(this.yAxis);
}
}
