I am printing numbers onto horizontal bars in a bar plots, but I am
finding it difficult to make the number always the right size. If there
are more bars, the bars get narrower and the font is too big. I also find
that if I change the size of the graph, the bars will get wider or
narrower and the font stays about the same size. The result depends on
whether I view the graph in X11 or in postscript.
Is there a way to specify font size relative to bar width, or at least
specify font size relative to graph coordinates?
Here's a bit of what I've been doing:
x.bar.plot <- barplot(as.matrix(x), horiz=TRUE, beside=TRUE, xlim=c(0,100),
xlab="Score", las=1)
text(as.matrix(x), x.bar.plot-.07, as.character(as.matrix(round(x))), pos=2,
col="black")
The "-.07" is something I added to make the numbers align well with the
bars under one condition, but it doesn't always help.
Any tips would be greatly appreciated. Thanks in advance.
Mike
