Question

由于某种原因，Chart的dataLabels仅显示在此深入分析的底层。 dataLabels设置为'column'。但是，它们不会显示每个呈现的列。

我需要更改什么才能让dataLabels在所有级别的钻取中显示？

感谢。

请参阅下面的代码和jsfiddle：

$('document').ready(function () {
var Drilldown = (function () {
    var chart,
    colors = Highcharts.getOptions().colors;

    function setChart(name, categories, data, color, type) {
        chart.xAxis[0].setCategories(categories);
        for (var i = 0; i < chart.series.length; i++) {
           chart.series[0].remove(true);
        }
        chart.addSeries({
            name: name,
            data: data,
            color: color || 'white'
        });
    }

        moneyLabel = {

实际上你的代码有点工作。数据标签行为不一致。当我在你的小提琴中玩耍时，数据标签肯定会在enabled: true中注释掉dataLabels并运行后消失。但是，如果我将其添加回来并再次运行，则数据标签会显示，隐藏在绘图区域内。由于数据标签使用与第一级列相同的颜色#89A54E，因此不太明显。

数据标签隐藏在列中的原因是您没有配置为处理数据标签为overflow时的情况。

如何处理在绘图区域外流动的数据标签。默认值为justify，它将它们在绘图区域内对齐。对于柱和条，这意味着它将在条内移动。要在绘图区域外显示数据标签，请将crop设置为false并溢出为“none”。默认为合理。

所以你需要做的是，将crop设置为false并溢出为“none”：

plotOptions: {
    column: {
        dataLabels: {
            overflow: 'none',
            crop: false,
            enabled: true,
            color: '#89A54E',
            style: {
                fontWeight: 'bold'
            },
            formatter: function() {
                return '$' + this.y
            }
         },
         // other configuration
}

Highcharts数据标签未显示在所有级别的向下钻取中
