my very sad bargraph

enter image description here

legend("topright", c("No Response", "Correct", "Incorrect"), 
        fill=c("#999999", "#33FF33", "#FF0000"))
legend("bottomright", c("No Response", "Correct", "Incorrect"), 
       fill=c("#999999", "#33FF33", "#FF0000"))

When I try to make it smaller I use cex=0.75, but all that does is make the legend smaller, it still sits on top of the data.

  • Does this answer your question? [Plot a legend outside of the plotting area in base graphics?](https://stackoverflow.com/questions/3932038/plot-a-legend-outside-of-the-plotting-area-in-base-graphics) – Paul Sep 21 '20 at 06:03

Base graphics doesn't naturally make room for legends and such (perhaps because it does not know you're planning on adding one). You can use xlim (and/or ylim) of the original plot in order to make room for it.

barplot(GNP ~ Year, data = longley)
legend("bottomright", c("No Response", "Correct", "Incorrect"), 
       fill=c("#999999", "#33FF33", "#FF0000"))

barplot, legend overlaid on data

par("usr")[1:2]
# [1] -0.56 19.96
barplot(GNP ~ Year, data = longley, xlim = c(0, 26))
legend("bottomright", c("No Response", "Correct", "Incorrect"), 
       fill=c("#999999", "#33FF33", "#FF0000"))

barplot, legend placed better
