问题
I am trying to change the font of axis and legend to serif but adding family='serif' did not work for the legend. How should I do it?
plot(sort(n.cdf),pch=3,cex = 0.5,xlab="Order",ylab="Cn",family="serif")
par(new=TRUE)
plot(sort(emp.c),col="red",pch=1,cex = 0.5,ann=FALSE, axes=FALSE)
par(new=TRUE)
legend( "topleft"
, inset = c(0,0.1)
, cex = 1
, bty = "n"
, legend = c("Simulated", "Empirical")
, text.col = c("black", "red")
, pt.bg = c("black", "red")
, pch = c(3,1)
, family=c("serif")
)
回答1:
Set the family plotting parameter before calling legend() to the value you want. Do this via an explicit call to par().
Here is an example:
x <- y <- 1:10
plot(x, y, type = "n")
text(x = 5, y = 5, labels = "foo", family = "serif")
## set the font family to "serif"
## saving defaults in `op`
op <- par(family = "serif")
## plot legend as usual
legend( ... )
## reset plotting parameters
par(op)
