AmCharts，捕获时段选择器的点击事件 [英] AmCharts, capturing click event for period selector

问题描述

我正在使用AmCharts 3，我想知道是否可以通过单击时段选择器的按钮来捕获事件?

I'm using AmCharts 3 and I was wondering is there a way to capture an event for clicking the buttons of the period selector?

文档状态，我可以向类型为'更改"，但事件几乎随时都可以运行

The Docs state I can add a listener to the period selector of the type 'changed' but then the event runs almost anytime

有一个"zoomed"监听器，但是无论我是否单击时段选择器，它都会在我每次缩放图表时运行

There is a listener for 'zoomed', but it runs every time I zoom my chart regardless if I clicked the period selector

这是我的尝试:

chart = AmCharts.makeChart(scope.vm.chartId, chartSettings);
    AmCharts.addInitHandler(function () {
    // add events to item
    _.each(chart.panels, function (item) {
    //item.addListener("zoomed", onZoomed);
    item.addListener("changed", function(e) {
    console.debug("changed " + e.periodString);
   });
 });
});

推荐答案

由于您是通过配置对象初始化的，因此建议您使用最新版本的AmCharts支持的新"listeners"属性将事件处理程序添加到chartSettings对象上的periodSelector对象.应该可以.

Since you are initiating through a configuration object, I suggest you use the new 'listeners' property supported in the latest version of AmCharts to add an event handler to the periodSelector object on your chartSettings object. It should work.
