How to increase the size of points in legend of ggplot2?
ggplot2, r

Add a `+ guides(colour = guide_legend(override.aes = list(size=10)))` to the plot. You can play with the `size` argument.
Problem
I have thousands of points in one figure and set `size = 1`. However, the point size in the legend is reduced too. How to increase the point size in the legend? For example. ``` num <- 10000 set.seed(1) df <- data.frame(x = seq(1, num), y = runif(num), z = rep(1:2, each = num / 2)) df$z <- factor(df$z) library(ggplot2) p <- ggplot(df, aes(x, y, colour = z)) + geom_point(size = 1) p ```
