我有一个图表类型为样条线的 Highcharts
在这张图表中，我有大约36个系列的数据，但问题是在一张图表中显示36个系列确实很难理解，而且几乎所有的数据都几乎相似。
我的问题是，我们如何才能只显示选定的或预定义的系列，而不是一次显示所有系列，这是 highcharts 默认情况下完成的。
另外，我不想更改正在获取 JSON 数据的 API，有什么方法可以从前端本身执行此操作吗？

我只是在将 JSON 数据注入(inject) Highcharts 之前对其进行操作。
假设您的 JSON API 返回系列数据数组...
// var series = getSeriesDataViaAjax();
var showTheseIndexes = [0,2,4];
for (var i = 0; i < series.length; i++) {
if (showTheseIndexes.indexOf(i) === -1) {
series[i].visible = false;
}
}
关于javascript - 仅显示 HighCharts 样条图中的某些系列，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30473296/
