Hello,

I have a file with the data in following format:

2014-04-24_10:00:00	1.2345
.............................

It is plotting cyclically, using reread command.
How to not plot whole file, but to make a "running window" of size, 
e.g., 30 minutes?

after each plot, a number of status variables is updated. You can check
them via

 show var GPVAL_

GPVAL_DATA_X_MAX keeps the maximum x from the last plot, so you can just

 set xrange [GPVAL_DATA_X_MAX-windowsize:*]

before replot.
