ggplot2将单条上的数字对齐 [英] Alignment of numbers on the individual bars with ggplot2
问题描述
我想在下图中的单杠上显示数字。 (结构(c(1L,1L,1L,2L,2L,2L,1L,1L) 3L,3L,
3L),。标签= c(0-50,000,50,001-250,000,250,001-过),等级=因子),
B =结构c(1L,2L,3L,1L,2L,3L,1L,2L,3L),。标签= c(0-50,000,
50,001-250,000,250,001- =因子),Freq = c(0.507713884992987,
0.258064516129032,0.23422159887798,0.168539325842697,0.525280898876405,
0.306179775280899,0.160958904109589,0.243150684931507,
0.595890410958904)),.Names = c(A ,B,Freq),class =data.frame,row.names = c(NA,
-9L))
library(ggplot2)
p < - ggplot(data = df,aes(x = A,y = Freq))+
geom_bar(aes(fill = B),position = position_dodge())+ theme_bw()
p< - p + scale_y_continuous(formatter =percent)
p < - p + geom_text(aes(label = paste(sprintf(%。1f,Freq * 100),%,sep =) ,y = Freq + 0.015,x = A),size = 3)
print(p)
我无法弄清楚如何将数字放在x轴的正确位置。任何帮助将非常感激。谢谢
您需要添加 position = position_dodge(width = 0.9)
给geom_text调用。
清理一下你的代码会给出:
p <-ggplot(data = df,aes(x = A,y = Freq))+
geom_bar(aes(fill = B),position = position_dodge())+
geom_text (aes(label = paste(sprintf(%。1f,Freq * 100),%,sep =),
y = Freq + 0.015,x = A),
size = 3,position = position_dodge(width = 0.9))+
scale_y_continuous(formatter =percent)+
theme_bw()
导致
I want to show numbers on the individuals bars in the following graph.
df <- structure(list(A = structure(c(1L, 1L, 1L, 2L, 2L, 2L, 3L, 3L,
3L), .Label = c("0-50,000", "50,001-250,000", "250,001-Over"), class = "factor"),
B = structure(c(1L, 2L, 3L, 1L, 2L, 3L, 1L, 2L, 3L), .Label = c("0-50,000",
"50,001-250,000", "250,001-Over"), class = "factor"), Freq = c(0.507713884992987,
0.258064516129032, 0.23422159887798, 0.168539325842697, 0.525280898876405,
0.306179775280899, 0.160958904109589, 0.243150684931507,
0.595890410958904)), .Names = c("A", "B", "Freq"), class = "data.frame", row.names = c(NA,
-9L))
library(ggplot2)
p <- ggplot(data=df, aes(x=A, y=Freq))+
geom_bar(aes(fill=B), position=position_dodge()) + theme_bw()
p <- p + scale_y_continuous(formatter="percent")
p <- p + geom_text(aes(label = paste(sprintf("%.1f", Freq*100), "%", sep=""), y = Freq+0.015, x=A), size = 3)
print(p)
I could not figure out how to put the numbers in the right position along x-axis. Any help will be highly appreciates. Thanks
You need to add position=position_dodge(width=0.9)
to the geom_text call.
Cleaning up your code a little gives:
p <- ggplot(data=df, aes(x=A, y=Freq))+
geom_bar(aes(fill=B), position = position_dodge()) +
geom_text(aes(label = paste(sprintf("%.1f", Freq*100), "%", sep=""),
y = Freq+0.015, x=A),
size = 3, position = position_dodge(width=0.9)) +
scale_y_continuous(formatter = "percent") +
theme_bw()
which results in
