[英]Relocate legend entries and axis labels in ggplot in R
嘿,我是R的新手,有一个非常小的问题
我有以下数据集:
head(risk_free_rate_comparison)
Dates ` Swap rate` `Sovereign bond yield rate` `Swap rate - Sovereign bond yield rate`
<dttm> <dbl> <dbl> <dbl>
1 2007-01-02 408.9 380.9568 27.9432
2 2007-01-03 410.3 380.4535 29.8465
3 2007-01-04 409.2 381.3993 27.8007
4 2007-01-05 414.3 385.0663 29.2337
5 2007-01-08 413.1 384.2545 28.8455
6 2007-01-09 415.5 384.9770 30.5230
,如下图:
ggplot(d, aes(Dates, value, color = variable, linetype = variable)) +
+ geom_line() +
+ labs(color = NULL, linetype = NULL) +
+ theme_classic() +
+ theme(legend.position = "bottom") +
+ ylab("Rates in bp")
我对图例的位置感到满意,但是是否可以使条目一个位于另一个的下方而不是并排放置?
此外,出于美观原因,我想将轴标签移离轴一点点。
最后添加我的theme()可以解决您的两个问题:
library(tidyverse)
mtcars %>%
mutate(am = factor(am, labels = c("auto", "manu"))) %>%
ggplot(., aes(wt, mpg, color = am, linetype = am)) +
geom_line() +
labs(color = NULL, linetype = NULL) +
theme_classic() +
ylab("Rates in bp") +
theme(
legend.position = "bottom",
legend.direction = "vertical",
legend.box.margin = margin(t = 30),
axis.title.x = element_text(margin = margin(t = 20))
)
