By the effect of "jitter", it seems can't control the relative position between of pair of label of geom_text and point of geom_point.
In the graph, I connect the pair which i can identify by black line. But, in fact, I almost can't make sure what are the correct pair due to the distance and related-position between label and point are dynamic.
Are there any master can offer some view to solve that problem?
Thanks so much!!
p4<-mpg.df %>% ggplot(aes(displ,hwy,color=cn))+ geom_jitter(shape=21,size=5,position=position_jitter(width=0.5,height=5))+ #geom_jitter(shape=21,colour=ifelse(as.numeric((rownames(mpg.df)))%%2==0,"red","green"),size=2,stroke=0.1,width=1,height=10)+ #geom_text(aes(label=rownames(mpg.df))) geom_text(aes(label=cn),size=2,position=position_jitter(width=0.5,height=5))+ guides(color=FALSE)
[i use black line to show the corresponding label and point, but almost can't identify all rest pair]
