是否可以在ggplot2中仅对条形图的一部分进行着色?
我想要交叉开关之间的彩色区域:“平均每日最大值”和“平均每日最小值”。
这是我的数据:
temperature <- read.table(text = 'X 1 2 3 4 5 6
1 "Highest temperature" 31 40 39 34 39 42
2 "Mean daily maximum" 27 34 32 30 34 35
3 "Mean daily minimum" 26 31 31 30 31 35
4 "Lowest temperature" 18 20 20 20 20 24', header =T)
t <- dcast(melt(temperature), variable~X)
ggplot(t, aes(x=variable,ymin = `Lowest temperature`,
ymax = `Highest temperature`, lower = `Lowest temperature`,
upper = `Highest temperature`, middle = `Mean daily maximum`)) +
geom_boxplot(stat = 'identity') +
xlab('Number') +
ylab('Temperature') +
geom_crossbar(aes(y = `Mean daily maximum` ))+
geom_crossbar(aes(y = `Mean daily minimum`))
答案 0 :(得分:4)
library(ggplot2)
library(reshape2)
read.table(
text = 'X 1 2 3 4 5 6
1 "Highest temperature" 31 40 39 34 39 42
2 "Mean daily maximum" 27 34 32 30 34 35
3 "Mean daily minimum" 26 31 31 30 31 35
4 "Lowest temperature" 18 20 20 20 20 24',
header = TRUE
) -> temperature
temp_long <- reshape2::dcast(reshape2::melt(temperature), variable~X)
ggplot(
temp_long,
aes(
x = variable,
ymin = `Lowest temperature`,
ymax = `Highest temperature`,
lower = `Lowest temperature`,
upper = `Highest temperature`,
middle = `Mean daily maximum`
)
) +
geom_boxplot(stat = 'identity') +
geom_rect(
aes(
xmin = as.numeric(variable)+0.45,
xmax = as.numeric(variable)-0.45,
ymin = `Mean daily minimum`,
ymax = `Mean daily maximum`
),
fill = "#a50f15"
) +
geom_crossbar(aes(y = `Mean daily maximum` )) +
geom_crossbar(aes(y = `Mean daily minimum`)) +
labs(x = 'Number', y = 'Temperature')
