我有这个情节:
library(ggplot2)
ggplot(iris,
aes(
x = Petal.Length,
y = Petal.Width,
color = Species,
linetype = Species,
shape = Species
)) +
geom_count(alpha = 0.20) +
geom_smooth(method = "lm", se = FALSE) +
labs(
color = "Species (Line)",
linetype = "Species (Line)",
shape = "Species (Points)"
) +
guides(
size = "none"
)
#> `geom_smooth()` using formula = 'y ~ x'
创建于 2023-11-02,使用 reprex v2.0.2
我正在尝试格式化图例,以便有一个具有点形状(也按颜色)的图例和一个单独的线型图例(也按颜色)。
我实际上得到的是一个仅用于形状(无颜色)的图例和一个具有彩色点的线型图例。我已经尝试了我能想到的图例标签的每一次迭代,但无济于事。
问题: 保持其他一切不变,我怎样才能摆脱物种(线)图例中的那些点?以及如何为形状添加颜色?
您需要删除颜色指南并覆盖形状和线型指南的美观:
library(ggplot2)
ggplot(iris,
aes(
x = Petal.Length,
y = Petal.Width,
color = Species,
linetype = Species,
shape = Species
)) +
geom_count(alpha = 0.20) +
geom_smooth(method = "lm", se = FALSE) +
labs(
linetype = "Species (Line)",
shape = "Species (Points)"
) +
guides(
size = "none",
color = "none",
shape = guide_legend(override.aes = list(alpha = 1,
color = scales::hue_pal()(3))),
linetype = guide_legend(override.aes = list(color = scales::hue_pal()(3)))
)
