Treat axis as date/time (epoch)
原标题:

I m generating a graph with gnuplot of activity over the last twenty four hours, but the time axis looks really bad because it s trying to fit the long number for every five minutes in the last day.

Is there any way for gnuplot to treat the x-axis as an epoch time, and mark every hour or so?

Is this what you want?

set xdata time
set timefmt "%s"
# set xtics 3600
set format x "%H:%M:%S" # or whatever
plot ...

i followed this from the gnuplot howto :

03/21/95 10:00 6.02e23

This file can be plotted by

   set xdata time
   set timefmt "%m/%d/%y"
   set xrange ["03/21/95":"03/22/95"]
   set format x "%m/%d"
   set timefmt "%m/%d/%y %H:%M"
   plot "data" using 1:3
