所以,我一直在试图利用深入到多个层面,我现在面临的问题是,我不能深入到第三级,因为该数据将通过在第二钻取的选择AJAX牵强。
例如,请参考此链接:
https://codepen.io/ajaymalhotra15/pen/aZpxXq
drilldown example
在这里,第三级是可能的,因为他已经有了数据,但是我的将取决于秒的选择。
那么,如何实现这一点,我应该在哪里调用ajax请求并动态设置下钻系列数据?

因此,在这里,如果您在plotoptions
中注意到,我正在尝试创建一个全新的图表,该图表是显示频率,电压和电流的同步线形图。
但是,我想我的方法不正确,因为我正在绘制新的图表。 因此,如何使此同步的折线图成为我的向下钻取的一部分。
如果您需要任何帮助以了解我,请告诉我。
我建议首先最小化plotoption
。然后扩展以进一步他妈的:P
谢谢。

您可以将所有逻辑用于获取第三级数据并在drilldown
事件中创建下钻系列:
chart: {
type: 'column',
events: {
drilldown: function(e) {
if (!thirdLevel.length) {
// get data
}
if (!e.seriesOptions) {
var chart = this,
drilldowns = {
'Animals': {
name: 'Animals',
data: [
['Cows', 2],
['Sheep', 3]
]
},
'Fruits': {
name: 'Fruits',
data: [
['Apples', 5],
['Oranges', 7],
['Bananas', 2]
]
},
'Cars': {
name: 'Cars',
data: [
['Toyota', 1],
['Volkswagen', 2],
['Opel', 5]
]
}
},
series = drilldowns[e.point.name];
chart.addSingleSeriesAsDrilldown(e.point, series);
chart.applyDrilldown();
}
}
}
}
