【问题描述】：
在我的网页上，我显示了 5 个带有可缩放 X 轴的不同折线图。每个图表还有许多系列，所有图表都相同。
我正在寻找控件，无论我更改哪个图表控件，您都可以在其中显示/隐藏在每个图表中发生的系列和缩放功能。
这是 Highcharts 支持的吗？

这非常接近我需要的谢谢！关于单击“组 1”或“组 2”按钮时如何获取事件的任何想法。一旦我发现，我可以在每个图表中按 ID 调用启用/禁用系列以链接所有按钮。
-
这也是我一直在寻找的，但我的 xAxis 是日期时间。 computeTickInterval 和 setTickInterval 函数可以使用日期时间格式吗？我有 4 个图表要同步，但所有图表的日期都是相同的。顺便说一句，上面的 jsfiddle 做得很棒。很流畅
-
@geomajor56 当然可以，它只是 xAxis 的其他格式。所以看看 setExtremes 函数（定义正确的范围），仅此而已。
-
你好@SebastianBochan，样品很棒..这正是我想要的。但是无论如何不要将“红线”显示为 Plot 而是使用图表的默认十字准线？谢谢
-
不，您只能使用渲染的路径。但在我的示例中，您可以通过编辑路径添加水平线。
有两种可能的解决方案：
最简单的选择是使用额外的按钮显示/隐藏和缩放。 因此，您将在页面中添加一些按钮并执行如下功能：
//编辑选择图表时出错：
您应该在创建图表时创建图表并将其添加到数组中。例如：
var charts = new Array();
var chart = new Highcharts.StockChart(opts);
charts.push(chart);
那么对于函数：
//Set xAxis extremes (zoom)
for (var i = 0; i < charts.length; i++) {
charts[i].xAxis[0].setExtremes(startDate, endDate);
}
更改缩放。 系列的显示和隐藏也很简单：
所以你可以调用charts[i].series[0].hide(); 来隐藏第一个系列
另一种可能性是在用户点击图表时使用 Highcharts 事件来启动类似的功能。
例如上图例：Highstock Options Reference
对于缩放：
xAxis : {
events : {
afterSetExtremes : afterSetExtremes
},
},
