My gnuplot login looks something like this:
1:00am 1 10
1:00am 30 12
1:01am 60 18
1:01am 90 20
1:02am 120 21
...
The first column contains (what I would like) the X axis labels, and the second column contains the X axis values. (Actually, I have one row per second, so many rows have “1:00 in the morning”, like in the column tags, then “1:01 AM”, etc.).
I can build the values that interest me using something like:
gnuplot> plot "my_data.txt" using 2:3 with lines
And I can set the X axis to a check mark (and label) every 30 minutes (which is 30 * 60 = 1800 seconds), but the label used is the value of the X axis (something like 3600 for one hour).
