使用ggplot2合并并完美对齐直方图和Boxplot [英] Merge and Perfectly Align Histogram and Boxplot using ggplot2
问题描述
从昨天开始,我正在阅读答案和网站,以便将一个直方图
和一个 boxplot
使用 ggplot2
包生成。
此问题与其他问题有所不同,因为 boxplot chart
需要减小高度
,并且对齐
到<$ c的左外边距$ c>直方图。
考虑以下数据集:
my_df<-structure(list(id = c(1,2,3,4,5,6,7,8,9,10,11,
12,13,14, 15、16、17、18、19、20、21、22、23、24、25、26、27,
28、29、30、31、32、33、34、35、36、37, 38、39、40、41、42、43,
44、45、46、47、48、49、50、51、52、53、54、55、56、57、58、59,
60、61、62、63、64、65、66、67、68、69、70、71、72、73、74、75,
76、77、78、79、80、81, 82,83,84,85,86,87,88,89,90,91,
92,93,94,95,96,97,98,99,100),值= c(18,9 ,3,
4、3、13、12、5、8、37, 64、107、11、11、8、18、5、13、13、14,
11、11、9、14、11、14、12、10、11、10、5、3、8, 11,12,11,7,
6,6,4,11,11,8,14,13,14,15,10,2,4,4,4,8,15,21,9,5,
7,11,6,11,2,6,16,5,5,21,33,12,10,13,33,35,7,
7,9,2,21,32, 19、9、8、3、26、37、5、6、10、18、5、70、48,
30、10、15、18、7、4、19、10、4、32) ),row.names = c(NA,100L
),class = data.frame,.Names = c( id, value))
我生成了箱形图:
require(dplyr )
require(ggplot2)
my_df%>%select(value)%&%;%
ggplot(aes(x =,y = value))+
geom_boxplot (填充=浅蓝色,颜色=黑色)+
coord_flip()+
theme_classic()+
xlab()+
theme(axis.text。 y = element_blank(),
axis.ticks.y = element_blank())
和我生成了直方图
my_df%>%selec t(id,value)%>%
ggplot()+
geom_histogram(aes(x = value,y =(..count ..)/ sum(.. count ..)),
position = identity,binwidth = 1,
fill = lightblue,颜色= black)+
ylab( Relative Frequency)+
theme_classic()
我想要获得的结果是一个单图,例如:
请注意,箱线图必须减小高度,并且标记必须完全对齐,以提供相同视觉效果的不同视角。
您可以使用 egg
, cowplot
或 patchwork
软件包来组合这两个图。有关更复杂的示例,另请参见
since yesterday I am reading answers and websites in order to combine and align in one plot an histogram
and a boxplot
generated using ggplot2
package.
This question differs from others because the boxplot chart
needs to be reduced in height
and aligned
to the left outer margin of the histogram
.
Considering the following dataset:
my_df <- structure(list(id = c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11,
12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27,
28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43,
44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59,
60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75,
76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91,
92, 93, 94, 95, 96, 97, 98, 99, 100), value= c(18, 9, 3,
4, 3, 13, 12, 5, 8, 37, 64, 107, 11, 11, 8, 18, 5, 13, 13, 14,
11, 11, 9, 14, 11, 14, 12, 10, 11, 10, 5, 3, 8, 11, 12, 11, 7,
6, 6, 4, 11, 8, 14, 13, 14, 15, 10, 2, 4, 4, 8, 15, 21, 9, 5,
7, 11, 6, 11, 2, 6, 16, 5, 11, 21, 33, 12, 10, 13, 33, 35, 7,
7, 9, 2, 21, 32, 19, 9, 8, 3, 26, 37, 5, 6, 10, 18, 5, 70, 48,
30, 10, 15, 18, 7, 4, 19, 10, 4, 32)), row.names = c(NA, 100L
), class = "data.frame", .Names = c("id", "value"))
I generated the boxplot:
require(dplyr)
require(ggplot2)
my_df %>% select(value) %>%
ggplot(aes(x="", y = value)) +
geom_boxplot(fill = "lightblue", color = "black") +
coord_flip() +
theme_classic() +
xlab("") +
theme(axis.text.y=element_blank(),
axis.ticks.y=element_blank())
and I generated the histogram
my_df %>% select(id, value) %>%
ggplot() +
geom_histogram(aes(x = value, y = (..count..)/sum(..count..)),
position = "identity", binwidth = 1,
fill = "lightblue", color = "black") +
ylab("Relative Frequency") +
theme_classic()
The result I am looking to obtain is a single plot like:
Note that the boxplot must be reduced in height and the ticks must be exactly aligned in order to give a different perspective of the same visual.
You can use either egg
, cowplot
or patchwork
packages to combine those two plots. See also this answer for more complex examples.
library(dplyr)
library(ggplot2)
plt1 <- my_df %>% select(value) %>%
ggplot(aes(x="", y = value)) +
geom_boxplot(fill = "lightblue", color = "black") +
coord_flip() +
theme_classic() +
xlab("") +
theme(axis.text.y=element_blank(),
axis.ticks.y=element_blank())
plt2 <- my_df %>% select(id, value) %>%
ggplot() +
geom_histogram(aes(x = value, y = (..count..)/sum(..count..)),
position = "identity", binwidth = 1,
fill = "lightblue", color = "black") +
ylab("Relative Frequency") +
theme_classic()
# install.packages("egg", dependencies = TRUE)
egg::ggarrange(plt2, plt1, heights = 2:1)
# install.packages("cowplot", dependencies = TRUE)
cowplot::plot_grid(plt2, plt1,
ncol = 1, rel_heights = c(2, 1),
align = 'v', axis = 'lr')
# install.packages("devtools", dependencies = TRUE)
# devtools::install_github("thomasp85/patchwork")
library(patchwork)
plt2 + plt1 + plot_layout(nrow = 2, heights = c(2, 1))
