Highcharts：从 CSV 加载数据时默认禁用系列

Question

我有一堆由 CSV 文件制成的图表，我希望默认情况下禁用某些系列。该系列是使用highcharts数据处理功能制作的，制作完成后我不知道如何定位它们。我试过了：

switch (plotOptions.series.name) { case "DACH - Austria, Germany and Switzerland": $(this.hide()); break; }

但这行不通。关于如何做到这一点的任何想法？我想写一个开关，因为默认情况下应该禁用 8/13 系列...下面的小提琴

Answer 1

您可以使用 chart.events.load 执行此操作：

chart: {
    events: {
        load: function () {
            var theSeries = this.series;
            $.each(theSeries, function () {
                if (this.index > 0) {
                    this.setVisible(false);
                }
            });
        }
    }
}

此示例仅检查系列的索引是否大于 0 并将可见性设置为 false，以便只有第一个系列在图表上可见。您可以根据需要在其中添加其他检查（例如 this.name）。
