KST Live Data

[Barth Netterfield]

Yes: Viewing data appended to a file is the intended use of kst. When 
the file grows, the new data will be read and the plots updated (when in 
count from end mode or read to end mode).

By default, kst reads white space separated collums of data.

eg, imaging a file called data.txt which contains

1  1
2  4
3  9
4  16

To read this you might enter from the command line:

kst2 data.txt -x 1 -y 2

Or you can read the file from the data wizard in the GUI.

As a side note, the documentation you referenced is obsolete, and refers 
to a very old version of kst.

The current documentation is at:
