如何设置圆形小平面包裹y轴的限制？

Question

我有这个情节,我需要围绕y轴,所以看起来是可以接受的除了我想不只是在y轴上显示1值的事实.我想在"scale_y_continuous"函数中添加"limit",以便每个facet图的限制对于各个facet是唯一的.

这里是仅在y轴上显示60和80的图

dat = data.frame(x = c(1,2,3,1,2,3),A=c(80.6, 82,83,60,61,62),A_up =c(81,84,85,62,63,64), A_low =c(79,78,81,59,58,57), group = c("z","z","z","y","y","y"))
ggplot(data=dat , aes(x=as.factor(x), y=A, group = 1)) + #, color =Group, group = Group 
  geom_line()  + geom_point() + # facet_wrap(~COUNTERPARTY_STRATEGY ,ncol=2)
  geom_errorbar(aes(ymax = A_up ,ymin = A_low), width = .25) +
     scale_y_continuous(breaks = seq(  floor(  (min(dat$A_low)-11)  /10)*10 ,
                                   ceiling(  (max(dat$A_up)+11) /10)*10,10 ),
                      labels = seq(  floor(  (min(dat$A_low)-11)  /10)*10 ,
                                   ceiling(  (max(dat$A_up)+11) /10)*10,10 )
                      ) +
    facet_wrap(~group ,ncol=2, scales = "free_y") 

现在我在比例y连续中添加限制,它全局应用限制.

dat = data.frame(x = c(1,2,3,1,2,3),A=c(80.6, 82,83,60,61,62),A_up =c(81,84,85,62,63,64), A_low =c(79,78,81,59,58,57), group = c("z","z","z","y","y","y"))
ggplot(data=dat , aes(x=as.factor(x), y=A, group = 1)) + #, color =Group, group = Group 
  geom_line()  + geom_point() + # facet_wrap(~COUNTERPARTY_STRATEGY ,ncol=2)
  geom_errorbar(aes(ymax = A_up ,ymin = A_low), width = .25) +
     scale_y_continuous(breaks = seq(  floor(  (min(dat$A_low)-11)  /10)*10 ,
                                   ceiling(  (max(dat$A_up)+11) /10)*10,10 ),
                      labels = seq(  floor(  (min(dat$A_low)-11)  /10)*10 ,
                                   ceiling(  (max(dat$A_up)+11) /10)*10,10 ),
                     # limits =  c( floor(  min(dat$A_low[dat$group =="z"])  /10)*10 ,ceiling(max(dat$A_up[dat$group =="z"])/10)*10 )   
                      #limits =  c( floor(  min(dat$A_low[dat$group =="z"])  /10)*10 ,ceiling(max(dat$A_up[dat$group =="z"])/10)*10 ) 
                      limits =  c( floor(  min(dat$A_low)  /10)*10 ,ceiling(max(dat$A_up)/10)*10 ) 
                      ) +
    facet_wrap(~group ,ncol=2, scales = "free_y") 

即

c( floor( min(dat$A_low) /10)*10 ,ceiling(max(dat$A_up)/10)*10 )

是50和90

但是我希望限制对于每个方面的情节都是独一无二的

所以正确的情节将有限制

c( floor( min(dat$A_low[dat$group =="y"]) /10)*10 ,ceiling(max(dat$A_up[dat$group =="y"])/10)*10 )

50和70

而左图将有限制

c( floor( min(dat$A_low[dat$group =="z"]) /10)*10 ,ceiling(max(dat$A_up[dat$group =="z"])/10)*10 )

70和90

如何将限制调整为特定于各个方面图？

dat = data.frame(x = c(1,2,3,1,2,3),A=c(80.6, 82,83,60,61,62),A_up =c(81,84,85,62,63,64), A_low =c(79,78,81,59,58,57), group = c("z","z","z","y","y","y"))


dat <- data.table(dat)

dat[, y_min := floor(  min(A_low)  /10)*10, by = group]
dat[, y_max := ceiling(max(A_up)/10)*10 , by = group]

ggplot(data=dat , aes(x=as.factor(x), y=A, group = 1)) + #, color =Group, group = Group 
  geom_line()  + geom_point() + # facet_wrap(~COUNTERPARTY_STRATEGY ,ncol=2)
  geom_errorbar(aes(ymax = A_up ,ymin = A_low), width = .25) +
  scale_y_continuous(breaks = seq(  floor(  (min(dat$A_low)-11)  /10)*10 ,
                                    ceiling(  (max(dat$A_up)+11) /10)*10,10 ),
                     labels = seq(  floor(  (min(dat$A_low)-11)  /10)*10 ,
                                    ceiling(  (max(dat$A_up)+11) /10)*10,10 )
  ) +
  facet_wrap(~group ,ncol=2, scales = "free_y") + 
geom_blank(aes(y = y_min)) + geom_blank(aes(y = y_max))

所以在这里我使用data.table by = group来创建y_min和y_max为每个组.然后使用这些值geom_blank来扩展绘图区域.

显然,这可以自动扩展到任意数量的组/方面.

我没有安装 ggplot，但也许一个简单的if () else可以解决你的问题。我的第一次尝试是这样的：

if {
(dat$group =="y") c( floor(  min(dat$A_low[dat$group =="y"])  /10)*10, ceiling(max(dat$A_up[dat$group =="y"])/10)*10 )

else c( floor(  min(dat$A_low[dat$group =="z"])  /10)*10,     ceiling(max(dat$A_up[dat$group =="z"])/10)*10 )
}
