大家好,我正在使用一个小数据框在
ggplot2
中构建一些绘图。我的数据框是 df
,我将其作为 dput()
添加到最后。我有情节,当我使用 patchwork
时,问题就出现了。我希望最终的图没有空格,以便中间的线(即轴)可以将图连接在一起。这是代码:
library(ggplot2)
library(patchwork)
library(cowplot)
library(ggtext)
#Plot 1
G1 <- ggplot(df,aes(x=Var1,y=Var2))+
geom_line(aes(color=Group,group=Group),size=1)+
geom_point(aes(color=Group,group=Group,shape=Group),size=2)+
scale_y_continuous(limits = c(0,NA),
sec.axis = dup_axis(name = '',breaks = NULL,labels = NULL))+
theme_half_open(12) +
background_grid() +
theme(
strip.background = element_blank(),
strip.text = element_textbox(
size = 12,
face = 'bold',
color = "white", fill = "#5D729D", box.color = "#4A618C",
halign = 0.5, linetype = 1, r = unit(5, "pt"), width = unit(1, "npc"),
padding = margin(2, 0, 1, 0), margin = margin(3, 3, 3, 3)
)
)+
theme(legend.position = 'top',
axis.title = element_text(color='black',face='bold'),
axis.text = element_text(color='black',face='bold'),
legend.text = element_text(color='black',face='bold'),
legend.title = element_text(color='black',face='bold'),
panel.grid = element_blank(),
legend.justification = 'center',
plot.margin = unit(c(0,0,0,0), "cm"),
plot.title = element_text(color='black',
size=12,
face='bold',hjust=0.5),
plot.caption = element_text(face='bold'))
#Plot 2
G2 <- ggplot(df,aes(x=Var1,y=Var3))+
geom_line(aes(color=Group,group=Group),size=1)+
geom_point(aes(color=Group,group=Group,shape=Group),size=2)+
scale_y_continuous(limits = c(0,NA),position = 'right')+
theme_half_open(12) +
background_grid() +
theme(
strip.background = element_blank(),
strip.text = element_textbox(
size = 12,
face = 'bold',
color = "white", fill = "#5D729D", box.color = "#4A618C",
halign = 0.5, linetype = 1, r = unit(5, "pt"), width = unit(1, "npc"),
padding = margin(2, 0, 1, 0), margin = margin(3, 3, 3, 3)
)
)+
theme(legend.position = 'top',
axis.title = element_text(color='black',face='bold'),
axis.text = element_text(color='black',face='bold'),
legend.text = element_text(color='black',face='bold'),
legend.title = element_text(color='black',face='bold'),
panel.grid = element_blank(),
legend.justification = 'center',
plot.margin = unit(c(0,0,0,0), "cm"),
plot.title = element_text(color='black',
size=12,
face='bold',hjust=0.5),
plot.caption = element_text(face='bold'))
#Merge plots
G3 <- G1+G2+plot_layout(guides = 'collect')&theme(legend.position = 'top')
这是
G3
的结果:
可以看出,由于中线和第二个图之间有空格,因此图未完全连接。我怎样才能删除那个空格?
非常感谢。接下来是数据
df
:
#Data
df <- structure(list(Var1 = c("A", "B", "C", "A", "B", "C"), Group = c("G1",
"G1", "G1", "G2", "G2", "G2"), Var2 = c(1L, 3L, 4L, 8L, 9L, 0L
), Var3 = c(9L, 8L, 4L, 5L, 1L, 1L)), class = "data.frame", row.names = c(NA,
-6L))
您可以调整
+ plot_layout(widths = c())
或者使用 & theme(plot.margin = ...)
调整边距,但是,我认为 plot.margin
在这种情况下不起作用。
要将
widths
实现到绘图中,您需要添加间隔图并使用 widths
调整间隔,使绘图完全连接在一起
G3 <- G1 + plot_spacer() + G2 + plot_layout(widths = c(4, -1.1 ,4.5),guides = "collect")& theme(legend.position = "top")
这里plot1的宽度是4,间隔图的宽度是-1.1,它允许你将图连接在一起,plot2的宽度是4.5。我不确定为什么plot2需要比plot1有更大的宽度,但是当它们的宽度都设置为4时,这两个图看起来不正确。
