Plotting time vs number

Hi,
...
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.

Hi Mohan,
Try this:

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,xaxt="n")
library(plotrix)
staxlab(at=as.numeric(strptime(data$Time,"%H:%M:%S")),
  labels=as.character(data$Time),nlines=3)
