time range

[Jacques B. <jac...@on...>]

Suppose you want to plot a 2D data-file the 1st column of which contain
times. For example:

gnuplot time.dem

time.dem:
     set timefmt '%s'
     set xdata time
     set format x "%y-%m-%d\n%H:%M:%S"
     set xrange ["1105190580":"1105190880"] # ok
     #tmin="1105190580"; tmax="1105190880"; set xrange [tmin:tmax]
     plot 'time.dat' using 1:2
     pause -1

time.dat:
     1105190640 2
     1105190700 1
     1105190760 3
     1105190820 0

You can set a time range with "set xrange" using explicit quoted
strings, but you can't do it with variables containing strings (ex:
tmin, tmax).

Would it be easy to implement this?
