具有多個 Y 軸值的動態樣條曲線 HighChart 示例 - Crunchify 提示

Highcharts 是一個用純 HTML5/JavaScript 編寫的圖表庫，為您的網站或 Web 應用程序提供直觀的交互式圖表。 Highcharts 目前支持折線、樣條、面積、arespline、柱、條、餅圖、散點圖、角規、arearange、aresplinerange、columnrange、氣泡圖、箱線圖、誤差線、漏斗圖、瀑布圖和極坐標圖類型。

最近我必須在動態樣條圖中添加另一個 Y 軸。 使用下面的簡單腳本，您可以非常輕鬆地添加第二個 y 軸。

演示

帶有兩個不同 Y 軸值的演示
