我无法减小此图中图例的大小。有人可以帮我吗？我希望它显示在顶部，但不超过绘图区域高度的 20%
a <- c(3, 2, 2, 2, 1, 2 )
barplot(a, beside = T,
col = 1:6, space = c(0, 2))
legend("topright", legend = c("a", "b", "c", "d", "e", "f"), fill = 1:6, ncol = 2)
最佳答案
cex参数会为你做到这一点。
a <- c(3, 2, 2, 2, 1, 2 )
barplot(a, beside = T,
col = 1:6, space = c(0, 2))
legend("topright",
legend = c("a", "b", "c", "d", "e", "f"),
fill = 1:6, ncol = 2,
cex = 0.75)
