Re: Customising Legend

[Dennis Murphy]

Hi:

This is a little extreme, but here's a toy example. Basically, you need to reduce the legend.key.height theme element. 

 DF <- data.frame(gp = factor(rep(LETTERS[1:3], each = 20)),

                   x = seq(20),

                   y = 0.5 + rep(0:2, each = 20) + 

                             0.3 * rep(seq(20), 3) + rnorm(60))

library('ggplot2')

library('grid')   # needed for the unit() function call below

ggplot(DF, aes(x, y, color = gp)) +

    geom_point() + 

    geom_smooth(method = lm, se = FALSE) +

    theme(legend.position = c(0.15, 0.82), 

              legend.key.height = unit(0.5, "mm"))

Does anyone have a workaround for adjusting the legend, to reduce the amount of white-space between legend items, without reducing the size of the font used.

In my work, I quite often place the legend inside the plot area, so that the outer bounds are preserved (for consistency), and, in this one instance, I want to reduce the footprint that the legend occupies within the main plot area.

Cheers.
