Bug 378403

Hi all

I wish to make a plot from two different data files using only the y columns (y vs y plot). In order to make myself clear:

I use the command prompt to load the data from two different files and make the x- and y- vectors as follows: i wish to use the 2nd column from the first file as x-vector, and the 2nd column of the second file as the y-vector.
Following the instructions i write:

kst data1.txt -x 2 data2.txt -y 2

However i don't get the desired. I get a y-vs-y both vectors from the same file (straight line). It seems that the program ignores one of the two files, although is stated clearly in the documentation that it should work:

https://www.mankier.com/1/kst2#Examples

"Get the X vector from data1.dat, and the Y vector from data2.dat.
      kst data1.dat -x 1 data2.dat -y 1"

Any idea??

Thank you
