When I run my code I get this error "Can't locate object method 'fetchrow_array' via package 'IO::File' at line 81 <_GEN_0> line 10." What am I doing wrong?
my $fh = IO::File->new_tmpfile or die "Unable to make new temp file: $
+!";
foreach $line (<FILE>)
{
~~~~~blah blah~~~~~~
}
my $data = GD::Graph::Data->new();
$data->read(file => ‘$fh’, delimiter => '\t');
$data = $data -> copy(wanted => [0, 1, 2
print <$fh>;
while (my @row = $fh->fetchrow_array()) <------line 81
{
$data ->add_point($row);
}
my $graph = GD::Graph::points->new();
$graph->set(
x_label => 'Time/Date',
y_label => 'Latency Count',
title => "Latency Graph between $center1 and $center2",
) or warn $graph->error;
my $image = $graph->plot($data) or die $graph->error;
open(IMAGE, ">graph.png") or die "Not able to open image file\n";
+
binmode IMAGE;
print IMAGE $image->png or die "Problem writing to image file\n";
