Hi everyone. I am new to R.
It will be greatly appreciated if someone can help me with the following
questions.
Here's the graph I have just produced.
http://www.nabble.com/file/p24732839/calibration.jpeg
(1) How can I put the legend on top of the grid lines?
It probably is on top. I guess you want white background as in:
legend(....., bg="white")
(2) How can I match the grid lines with the x-axis ticks?
grid() does exactly that for me, so I guess you are not using base
graphics, hence please provide reproducible code as the posting guide
suggests!
(3) How can I change the x-axis format from e.g. Mar, Apr...etc to
1-3-2009,1-4-2009...etc?
One way is to specify the x-axis separately, but since we do not know
how you produced that plot ....

Many thanks! :-)
