java-Apache POI-无法获得折线图值以显示在辅助轴中
作者：互联网
我无法使折线图值显示在图表的辅助轴上.
当我打开excel文件时,只要用右键单击线系列的顶部并选择“格式化数据系列”,就可以按我想要的方式获得图表,似乎选择了辅助轴,但是我的图表却没有不是我想要的方式,当我选择主轴然后再次选择辅助轴时,它会起作用.这没有道理.
如果有将ValAx放置在辅助轴中的功能会很好,但是您只能说向右或向左,这对我没有帮助.
这有点像我的代码

解决方法:
您需要使用CTCrosses设置值轴与类别轴相交的位置.默认情况下,它与STCrosses.AUTO_ZERO相交.但是,辅助轴必须与类别轴的最大值相交.
STAxPos R并不意味着轴位于图表的右侧,而是轴标签位于右侧.
