[英]How to add labels to a stacked bar graph
我希望將數值添加到我生成的堆疊條形圖中每個堆棧的中間(代碼如下)。 我發現的大多數示例都是針對一列中的信息的,每當我嘗試修改它時,都會遇到有關長度要求的錯誤。
DA <- data.frame(
Imp=c("2015","2019"),
"mismatch"=c(220,209),
"match"=c(3465,3347),
"NA"=c(501,630),
check.names = FALSE)
DA %>%
pivot_longer(-Imp) %>%
ggplot(aes(x = Imp, y = value, fill = name)) + geom_col(position = "stack") +
scale_fill_manual(name=" ", values=c("aquamarine4", "orange", "coral")) +
theme_light() +
theme(legend.position = "bottom") +
scale_y_continuous(expand = c(0,0)) +
geom_text(aes(x=1, y=4300, label="Stretch it"), vjust=-1) +
labs(y="Count", x="Imputed Genotypes") +
geom_bar(stat = "identity", color="white", width = 1)
像這樣?
library(tidyverse)
DA <- data.frame(
Imp=c("2015","2019"),
"mismatch"=c(220,209),
"match"=c(3465,3347),
"NA"=c(501,630),
check.names = FALSE)
DA %>%
pivot_longer(-Imp) %>%
ggplot(aes(x = Imp, y = value, fill = name)) +
geom_col(color = "white", lwd = 1,
position = "stack", width = 0.75) +
scale_fill_manual(name="", values=c("aquamarine4", "orange", "coral")) +
scale_y_continuous(expand = c(0,0),
limits = c(0, 4200)) +
labs(y="Imputed Genotypes (Count)") +
geom_text(aes(label = value), color = "white", size = 5,
position = position_stack(vjust = 0.5),
show.legend = FALSE) +
theme_light(base_size = 18) +
theme(legend.position = "right",
axis.title.x = element_blank())
