in reply to loops + creating graphs

Each time you produce a new graph, your writing it to the same file!

      Use different file names:)

      See Automatically creating incremental file names for recent discussion on this very problem.

      i think what you want to do is create a temporary file; that way, you can store the plot data in it. and not have it overwritten.

      according to the cookbook, you could use tmpnam. there was a posting with that in the last couple of days (check "newest nodes"). i prefer File::Temp.

      something like 
      use File::Temp;
my $tfname = File::Temp::tempnam($tmpdir, "math.")

      will get you *the name* for a create a temporary file with the prefix "math". you'll have to write the stuff in the loop to it yourself.
