#570 — Newbie queries

Hi,

I have a data file as follows:

Time data
00:00:00 123456
00:00:30   7890123
:
23:59:59  234567

Currently, I inserted a new column from 0 with increment of 30 to the
end and I plotted the graph with 1:3.

If I want to use HH:MM:SS to display for x-axis, how to go about it to
plot the graph?

Thanks in advance.

You could have avoided the modification by using pseudo-column 0 instead...

See "help time/date"

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?

Thanks, it is working but when I applied the steps with a record with
86000+ rows (set xrange ["00:00:00":"23:59:59"]), the x-axis displays
01/01 to 02/01 instead?
