In gnuplot, how to label each point in the plot with its coordinates? -

i have data file, abc.dat , want plot labeling each coordinate (1,5), (4,6), (2,8) , on ....

abc.dat :

1  5 4  6 2  8 4  5 7  8 8  9 3  4

use labels plotting style this. requires 3 using specifiers: x-value, y-value , string placed @ given coordinates. easiest command be:

plot 'abc.dat' using 1:2:(sprintf("(%d, %d)", $1, $2)) labels notitle

that places respective labels centered @ coordinates.

the following command plots point @ respective coordinate , places coordinate label bit shifted near it:

set offset 1,1,1,1 plot 'abc.dat' using 1:2:(sprintf("(%d, %d)", $1, $2)) labels point  pt 7 offset char 1,1 notitle

the result 4.6.4 is:
