具有多个 Y 轴的动态样条 HighChart 示例

具有多个 Y 轴值的动态样条曲线 HighChart 示例 - Crunchify 提示

Highcharts 是一个用纯 HTML5/JavaScript 编写的图表库，为您的网站或 Web 应用程序提供直观的交互式图表。 Highcharts 目前支持折线、样条、面积、arespline、柱、条、饼图、散点图、角规、arearange、aresplinerange、columnrange、气泡、箱线图、误差线、漏斗图、瀑布图和极坐标图类型。

最近我必须在动态样条图中添加另一个 Y 轴。 使用下面的简单脚本，您可以非常轻松地添加第二个 y 轴。
