对于合并线型和色标的绘图，我很难制作出组合图例来显示所有四个选项。我看过this answer，但是，正如您在运行绘图代码时会发现的那样，这似乎不起作用-我得到正确的分类，但是无法打印图例的所有四个元素。我在做什么错了？
谢谢！

答案 0 :(得分：1)
尝试一下。对正在使用的两个字段（mutate(hybrid = paste(Meteorological_Season_Factor, Treatment))进行散列，然后将其用于颜色和线型（aes(...col = hybrid, linetype = hybrid)），然后对两个{{1 }}函数。
这是您要找的东西吗？ （P.S.我相信我按您使用标签和值的顺序使用了它们……也许唯一的问题是您已经换了其中的一些！）
