Highcharts中的捕捉平移事件

问题描述

用户平移图表时是否可以捕获事件?

Is it possible to catch event when user is panning on chart?

我已将Highcharts选项设置为:

I've Highcharts options set to:

chart: {
  panning: true,
  panKey: 'shift',
  events: {}
}

在事件对象中，选择有效.在文档中，没有关于窗格事件的任何信息.

In events object, selection is working. In the documentation, there's nothing about pane event.

是否有办法赶上此事件?

Is there a way to catch this event anyway?

推荐答案

默认情况下，Highcharts不提供此类事件.

Highcharts doesn't provide that kind of event by default.

此问题的解决方法是包装核心pan函数:

The workaround for this is to wrap the core pan function:

(function(H) {
  H.wrap(H.Chart.prototype, 'pan', function(proceed) {
    console.log("panning...");
    proceed.call(this, arguments[1], arguments[2]);
  });
})(Highcharts);
