我一直无法发现如何在图表右侧添加第二个相同的 y 轴。作为一个附带问题，我不知道如何切换 y 轴在哪一侧。时期。
我调查过multiChart type, but it seems as though a data series must be assigned to a specific axis; if I only have one series, the second axis does not show. I have thought about assigning the same series to both axis by duplicating the series, but this is terrible work around.
使用一个（或多个）系列时，在折线图的左右两侧实现两个相同 y 轴的正确解决方案是什么？
