The following code causes an unwanted cross effect in the legend.
ggplot() +
geom_vline(aes(xintercept=1,colour="vertical"), show.legend = NA) +
geom_hline(aes(yintercept=1,colour="horizontal"), show.legend = NA)
I read several posts which say that adding show.legend = NA
could make this effect go away, but this isn't working in my case.
Edit: To avoid confusing, I don't want the legend to go away! I just want the "cross" in the legend to go away, so it should show items like:
and
I agree that fixing legends up can get tricky. For this example, simply put show.legend = FALSE
for the ONE line you do not want.
library(ggplot2)
ggplot() +
geom_vline(aes(xintercept=1,colour="vertical"), show.legend = F) +
geom_hline(aes(yintercept=1,colour="horizontal"))
Okay here is attempt 2. It is pretty ugly; it crams two legends into one plot. It looks pretty close to what you want.
library(ggplot2)
p1 <- ggplot() +
geom_vline(aes(xintercept=1,colour="vertical"))+
scale_color_manual(values = "#619CFF")
p2 <- ggplot()+
geom_hline(aes(yintercept=1,colour="horizontal"))
l1 <- cowplot::get_legend(p1)
l2 <- cowplot::get_legend(p2)
p3 <- ggplot() +
geom_vline(aes(xintercept=1,colour="vertical")) +
geom_hline(aes(yintercept=1,colour="horizontal"))+
theme(legend.position = "none")
l3 <- cowplot::plot_grid(l1, l2, ncol = 1, align = "v")
cowplot::plot_grid(p3, l3, nrow = 1, align = "h", rel_widths = c(1, 0.2))
