#按照分组进行排序

Calculate the z-score of the mpg data:

df$mpg_z <- (df$mpg -mean(df$mpg))/sd(df$mpg)
df$mpg_grp <- factor(ifelse(df$mpg_z < 0, "low", "high"),levels = c("low", "high"))
p<-ggbarplot(df,x="name",y="mpg_z",fill="mpg_grp",color="white",x.text.angle = 90 ,sort.by.groups = F,sort.val = "asc",palette = "jco",ylab = "MPG z-score",xlab = FALSE,legend.title = "MPG Group")
p

Rotate the plot: use rotate = TRUE and sort.val = “desc”

p<-ggbarplot(df,x="name",y="mpg_z",fill="mpg_grp",color="white",x.text.angle = 90 ,sort.by.groups = F,sort.val = "desc",palette = "jco",ylab = "MPG z-score",xlab = FALSE,legend.title = "MPG Group",rotate = TRUE,ggtheme = theme_minimal())

Dot charts

           color = "cyl",                                # Color by groups

           sorting = "ascending",                        # Sort value in descending order
           add = "segments",                             # Add segments from y = 0 to dots

Sort in decending order. sorting = “descending”.
Rotate the plot vertically, using rotate = TRUE.
Sort the mpg value inside each group by using group = “cyl”.
Set dot.size to 6.
Add mpg values as label. label = “mpg” or label = round(df$mpg).

p1<-ggdotchart(df, x = "name", y = "mpg",
           color = "cyl",                                # Color by groups
