我正在尝试使用vue js复制此图表http://jsfiddle.net/edzk8Loe/。
说实话，我正在学习vuejs，因此我正在尝试复制已经准备好的项目，以便迅速获得信心。
我现在所面临的问题是一个逻辑问题。这些功能必须在单击列时创建新系列作为向下钻取，接缝根本不会触发。我在控制台中没有任何错误，我是
关于结构，我还没有一个很清楚的想法，我想我正在弄乱代码。在下面，您将找到我在VUE中使用的代码。

您在代码中犯了几个简单的错误。
1）向图表方法中添加updateGraph函数-这样您就可以在追溯回调中调用此方法
2）将图表组件引用保存在图表对象中，以便能够使用钻取回调函数中的updateGraph方法。您可以使用mounted()钩子来实现它：
mounted() {
this.$children[0].chart.vueRef = this;
}
3）数据应该是一个返回具有属性的对象的函数：
data() {
return {
chartOptions,
drilldownChart,
drilldownEvent,
drilldownLevel
}
}
4）将drilldown和drillup回调添加到chart.events对象。在那里，您可以从保存在安装的挂钩中的图表组件引用中调用updateGraph方法：
chart: {
"type": "column",
events: {
drilldown: function(e) {
if (!e.seriesOptions) {
this.vueRef.updateGraph(true, this, e);
}
},
drillup: function(e) {
if (!e.seriesOptions.flag) {
this.vueRef.drilldownLevel = e.seriesOptions._levelNumber;
this.vueRef.updateGraph(false);
}
}
}
}
