【问题描述】:
我正在尝试显示包含未检测到的数据。对于 ND,我希望有一个不同大小的圆形轮廓,这样线条就不会相互重叠。我几乎有我想要的东西,但是对于参数 cis-DCE,圆形轮廓只会使点看起来更大,而不是成为一个独特的轮廓。如何将大小归因于参数并同时使起始大小变大?
我将包含我用于绘图的所有代码,但我现在正在专门处理这一点。
geom_point(aes(x= date, y = lrl, group = parm_nmShort, size = parm_nmShort), shape = 1) + #marking lower limit
我也知道我可以使用 facet_wraps 并且我之前已经这样做了,但从历史上看,这些数据已显示在一个图表中,但没有识别 ND,我不想大幅改变数据的显示和混淆任何人。
