I have a test.csv with two fields "year" and "sale", with below values:

year   sale
2001    1002002    200

This is what I did in R.
But when I call the above plot function why I'm getting decimals in x-axis
(year) ex: 2001.0, 2002.05

Please help.

Hi,

Since you didn't provide a reproducible example, we have no way of knowing.

But if I were you, I'd start with
str(aaa)
because my first guess is that your data import did not work as you expected.

My guess is that perhaps
  plot(aaa$year, aaa$sale)
will produce something closer to what was expected.

this got fixed when I added 3 more rows to my existing test.csv file, i.e.
new file got below data, with additional 3 rows:

   year   sale
    2001  100
    2002  200
    2003  300
    2004  400
    2005  500

What's the secret behind 5 rows , i mean is there any link between plot
chart and 5 values ?
If I use less than 5 rows, it's breaking x-axis values into 5 decimals !!!

Hope you understood what I've told, if not, let me know...will provide you
reproducible steps.

Many Thanks.

Hi

Plot calls function pretty which calculates values for annotating axes.

You can get rid of this behaviour by

plot(..., axes=FALSE)

and calling
axis(1, ...)

see

?plot
?pretty
?axis

Cheers
