I need to sort the data in both X and Y column simultaneously, to get ordered pairs (X,Y) from smallest to largest.

sort -k1,1n -k2,2n inputdata.dat
did not work

RE: Sort 2d histogram data smallest to largest

how should the result (for the data above) look like ?

RE: Sort 2d histogram data smallest to largest

(OP)
It should be min(X,Y) to max(X,Y)

6.5 -1.25 10.2804
6.5 -1.21717 10.3285
etc

No value must decrease in subsequent records. I need the data in R which requires incremantal X, Y ordering.

RE: Sort 2d histogram data smallest to largest

(OP)
Currently the data decreases in periodic repetition

I need to sort simultaneously X and Y to get rid of this order.

RE: Sort 2d histogram data smallest to largest

I tried:

CODE

$ export LC_ALL=C
$ sort -k1 -k2 -n inputdata 

and got the data sorted:
