I'm having trouble getting a "time friendly" X-axis layout in Gnuplot.
I need to present some data referring to a period within one day; the time X data is represented in decimal form, e.g. X=20.75 meaning 20 hours and 45 mins, the range is generally [0 : 24], but normally a subset, such as [2.25 : 8.75].
The default Gnuplot x-axis layout will be something like the range [0 : 25] with major tics at 0,5,10,15,..., which is nice for normal decimal data, but I would like it to choose something more "time friendly" in the usual clock manner, I mean major ticks at hours 1,2,3 or 6 and minor ticks at 1,5,15 or 30 minutes, suitably chosen depending on the range.
Does anybody know how to do that?
