我想从ggplot的填充图例中删除颜色线。我通常使用guide_legend(override.aes = ...)
来修改传奇美学 - 适用于点,线,alpha等,但它不适用于我的color
美学。我做错了什么?
# generate data
set.seed(47)
data = data.frame(year = rep(2000:2004, 3),
value = runif(15),
group = rep(c("A", "B", "C"), each = 5))
# create the plot
p = ggplot(data, aes(x = year, y = value, fill = group)) +
geom_area(position = position_fill(), color = "white") +
scale_fill_grey()
# this should modify the fill legend to remove the colored line
# but the line is still there
p + guides(fill = guide_legend(override.aes = list(color = NA)))
