删除图例中的 space (ggplot)
Removing space in legend (ggplot)
我想删除下图(红色矩形)图例中的space。如何删除此 space?
图
代码
ggplot(C, aes(x = sigma, y = value, group=name)) +
geom_line(aes(linetype=name)) +
scale_linetype_manual(values=c("solid", "twodash", "dotted")) +
theme_minimal() +
theme_classic() +
theme(legend.position = c(0.15, 0.85),
legend.background = element_rect(fill="white",
size=0.5,
linetype="solid",
colour ="gray"),
text = element_text(size=20),
legend.text = element_text(size=20),
axis.title=element_text(size=20),
legend.title = element_blank(),
panel.grid.major.y = element_line(),
panel.grid.minor.y = element_line())
您可以通过设置 legend.spacing.y = unit(0, "pt")
来移除图例条目和背景框之间的白色 space。如果那仍然是太多的白色 space 你可以尝试使用负值或通过 legend.margin
:
减少上边距
使用 ggplot2::economics_long
作为示例数据:
library(ggplot2)
ggplot(subset(economics_long, variable != "pop"), aes(x = date, y = value)) +
geom_line(aes(linetype=variable)) +
scale_linetype_manual(values=c("solid", "twodash", "dotted", "solid", "twodash")) +
theme_classic() +
theme(legend.position = c(0.15, 0.85),
legend.background = element_rect(fill="white",
size=0.5,
linetype="solid",
colour ="gray"),
legend.spacing.y = unit(0, "pt"),
text = element_text(size=20),
legend.text = element_text(size=20),
axis.title=element_text(size=20),
legend.title = element_blank(),
panel.grid.major.y = element_line(),
panel.grid.minor.y = element_line())
