About Time labels, I have tried you mentioned method , but It still show oddness number
I have an example . Mybe It  can explain my meaning clearly.
Thank you for helping me!

Time <- c("2004-08-05 09:08:48", "2004-08-13 20:53:38",
  	"2004-08-14 13:57:23", "2004-08-12 16:17:41", 
  	"2004-08-12 16:15:27", "2004-08-11 21:38:24",
  	"2004-08-12 14:28:41", "2004-08-18 18:04:47",
  	"2004-08-13 15:23:14", "2004-08-14 02:36:33")
Time <- as.POSIXlt(Time)
x <- data.frame(main.name="AAA", fruit.name=rep(c("Apply","Watermelon"),each=5), 
		x.name=Time, y.name=(1:10))
fruit.class <- table(x$fruit.name)
color.code <- c(611,552,656,121,451,481,28,652,32,550,90,401,150,12,520,8)
for(j in 1:length(fruit.class))
	fruit <- names(fruit.class)[j]
	lines(smooth.spline(x[x$fruit.name==fruit, "x.name"],
		x[x$fruit.name==fruit, "y.name"],df=5),

If you are trying to cram a lot of labels on an axis, the "staxlab" function 
in the "plotrix" package may help you.

This looks like a date problem. The date is being converted to one of the 
"seconds-since-x" timescales and printed as that value. Try converting your 
original dates to labels using "as.character".
