r - 将 Geom_points ggrepel 标签与辅助轴对齐

Question

我的 geom_points ggrepel 标签未与辅助轴对齐。它正在获取主轴的数字。我该如何改变它？

与上一个问题相同。1000 * BASE_SHARE错过了使用geom_label_repel

draw <- ggplot(BHAGWANPUR, aes(x=PARTY, y=DELTA_VOTES, label=DELTA_VOTES)) +
  geom_bar(stat='identity', width=.5,aes(fill=PARTY))+geom_text(aes(label=DELTA_VOTES,vjust="top"),position = position_stack(vjust = 0.5))+
  scale_fill_manual(values=c("#00BFFF","#F98C1F","#22409A"))+labs(subtitle="2012 to 2017", 
                                                                  title= "Bhagwanpur,Uttarakhand") +
  theme(panel.grid.major = element_blank(), panel.grid.minor = element_blank(),
        panel.background = element_blank(), axis.line = element_line(colour = "black"))

draw <- draw+geom_point(colour = c("#00BFFF","#F98C1F","#22409A"),data = BHAGWANPUR, aes(x=PARTY, y=(BASE_SHARE * 1000),group = 1))+geom_label_repel(
  aes(PARTY, BASE_SHARE * 1000, label = BASE_SHARE),
  fontface = 'bold', color = 'black',
  box.padding = unit(0.35, "lines"),
  point.padding = unit(0.5, "lines"),
  segment.color = 'grey50'
) +
  geom_line(data = BHAGWANPUR, aes(x=PARTY, y=BASE_SHARE * 1000,group = 1), stat="identity")+
  scale_y_continuous(name = "Votes", sec.axis = sec_axis(~./2000, name = "Base Share",labels =  function(x) paste0(x, "%")))
