Code: (dl )

  my $gd = $graph->plot(\@data) or die $graph->error;

Then do whatever your current version of GD allows you to do to save the file. For versions of GD older than 1.19 (or more recent than 2.15), you'd do something like:

Code: (dl )

1
2
3
4

  open(IMG, '>file.gif') or die $!;
  binmode IMG;
  print IMG $gd->gif;
  close IMG;

and for newer versions (1.20 and up) you'd write

Code: (dl )

1
2
3

  open(IMG, '>file.png') or die $!;
  binmode IMG;
  print IMG $gd->png;

or

Code: (dl )

1

3

  open(IMG, '>file.gd2') or die $!;
  binmode IMG;
  print IMG $gd->gd2;
