I have been trying to draw histogram for my manscript and found some strange
things that I could not figure out why.
Using the same code listed below I have successfully draw histograms for a
few figures with fraction labeled on Y axis less than 1 (acturally between 0
to 0.1). But one dataset gives the Y axis label 0 to 5 as fraction. This
is not true, as fraction are less than 1, although the value distribution on
the figure seems to me is right.
The only difference between the first few datasets and last dataset is:
All values for the first few data sets > 1.
The values for the last data sets between 0 and <1.
Any idea why this happens.
Your help is highly appreciated.

postscript("Figure.eps", paper="letter", horizontal=FALSE)
par(mfrow=c(3,3))
par(omi=c(2,0.2,1.8,0.2), mai=c(0.4, 0.4, 0.5, 0.1) )
my.input <- read.table("input.data", header=FALSE, sep="\t")
my.input.exp <- read.table("exp.data", header=FALSE, sep="\t")
hist(my.input.exp[,2], breaks=40,freq = FALSE,xlab="", border = "grey30",
ylab="", main="")
hist(my.input[,2], breaks=40,freq = FALSE,xlab="", ylab="", main="", border
= "red",add =TRUE)
mtext("Fraction", side=2, line=2, cex=0.7)
box()
