Hello dear list,
I just cannot figure out how to do this and didn't find a solution for my
specific problem.
I want to place a centered horizontal legend between 4 plots. That's no problem.
The problem is: As soon as I specify the "text.width" parameter to separate the
two legend entries, the legend is not centered anymore. I thought the 'xjust' parameter
would do what I want, but it doesn't change a thing :(
Please see this minimal example:
# Setting up the layout of plots
layout(matrix(c(1,2,3,3,4,5), nrow = 3, byrow = T), heights = c(1,0.1,1))
par(mar = c(4.3,4,2,1.5))
# plot 1
plot(rnorm(100))
# plot 2
plot(rnorm(100))
# legend as plot no.3
par(mar = c(0,0,0,0))
plot.new()
legend(x = "center", lty = c("solid", "dashed"), horiz = T,
legend = c("Beginning", "End"), lwd = 2, bty = "n", text.width = 0.2)
par(mar = c(4.3,4,2,1.5))
# plot 4
plot(rnorm(100))
# plot 5
plot(rnorm(100))
Hi Sascha,
It's a rather nasty kludge, but you might be able to use this:
legend(x="center",lty=c("solid",NA,"dashed"),horiz=TRUE,
legend=c("Beginning"," ","End"),lwd=2,bty="n")
