I tried using the following text file:

01:00:00  310
01:00:30  185
01:01:00  239
01:01:30  132
01:02:00   85
01:02:30   57
01:03:00    8


set xdata time
set timefmt "%H%M%S"
set xrange ["01:00:00":"03:00"00"]
plot "file" using 1:2 with boxes

The result does not show the graph, were did I done wrongly?
