如何删除添加到图例中的斜线?还有黄色和灰色上的点...为什么会发生这种情况?
library(ggplot2)
x <- seq(from = 1, to = 10, by = 1)
df = data.frame(x=x, y=x^2, v=2*x)
df2 = data.frame(x=x, y=x^2-5*x-10)
ggplot(df, aes(x, y)) +
geom_point(aes(size = v)) +
theme_classic() +
scale_size("blabla") +
geom_point(data=df2, aes(x, y, color = "blue")) +
geom_line(data=df2, aes(x, y, color = "blue")) +
geom_hline(aes(color="gray",yintercept=25)) +
geom_abline(aes(color="yellow", intercept=0, slope=1)) +
scale_color_manual(values = c("blue","gray","yellow"), labels = c("nanana","hhh","abab"), name = "other")
最佳答案
这是color
美学的图例,它尝试结合geom_point
、geom_line
、geom_hline<的所有所需信息
和 geom_abline
。为了摆脱线条,我们需要
geom_abline(aes(color = "yellow", intercept = 0, slope = 1), show.legend = FALSE)
而对于点,我们必须添加
guides(color = guide_legend(override.aes = list(shape = c(19, NA, NA))))
这给出
