Hi,

plot(strptime(data$Time,"%H:%M:%S"),data$Kbytes,pch=0,type="b",col = 
"red", col.axis="red", ylab="", xlab="",las=2,lwd=2.5,cex.axis=1.5)
title("",cex.main=3,xlab="Seconds", line=5.2,ylab="Kbytes", cex.lab=2,1)

Hope I am not simplifying this in a bad way. These  lines plot everything 
properly except the number of labels on the x-axis. 

The plots are all there but the x=axis labels are not there. The graph 
labels are only '12:30', '13:30' and '14:30'

I think I need to use your code to get all the values.

If I don't show working code I don't get any response from the forum. So I 
need basic code to show how it works :-)

Thanks,
Mohan

What you need to do is to create the plot without an x-axis (xaxt =
'n') and then add your own values on the axis with 'axis'


x <- read.table(text = "      Time  Kbytes     RSS Dirty_Mode
1 11:42:02 2691296 1599796    1582736
2 11:43:42 2691396 1599804    1582744
3 11:45:22 2691496 1599804    1582744
4 11:47:02 2691596 1599812    1582752
5 11:48:42 2691696 1599816    1582756
6 11:50:22 2691796 1599820    1582760", as.is = TRUE, header = TRUE)
x$tod <- as.POSIXct(paste('2013-08-28', x$Time))
plot(x$tod,x$Kbytes,type="b",col = "blue",  ylab="", xaxt = 'n',
xlab="",las=2,lwd=2.5, lty=1,cex.axis=1.5)
# now plot you times
axis(1, at = x$tod, labels = x$Time, las = 2)

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.
