Re: plotting two sets of random points

[Bastian M. <bma...@we...>]

Or, if you use the current CVS version, you could use loops to generate 
a data file:

   set print "points.dat"
   print "# dataset 1"
   do for [i=1:100] { print rand(0), rand(0) }
   print ""; print ""
   print "# dataset 2"
   do for [i=1:200] { print rand(0)+3, rand(0)+3 }
   unset print
