如何在绘图的第二个主标题行中更改字体大小

Question

In addition to this question ( How to split the Main title of a plot in 2 or more lines? ) I tried to give the second main title line another font size. cex.main=1 only varies the entire main title.

So I haven't found anything how it could work…

Has anyone some hints?

Many thanks in advance!

My code:

    plot(1, main=paste("X:",1," ","Y:", 2," ","\nZ:",3)) # the “Z: 3” should get a smaller font size

Answer 1

Alternative to adding second main title and increase font size would be to use title() with plot() . With title() you could also add and manipulate position of "second title" and also font type.

So the code looks like this:

    plot(1, main = paste("X:",1," ","Y:", 2," ")) 
   # In order to change font size use cex.main and in order to manipulate 
   # the position of second title use line()
  title(main = ("Z: 3"),  line = 0.5, cex.main = 0.8)

And the output (font of Z: 3 is smaller)
