johnirl has asked for the wisdom of the Perl Monks concerning the following question:
I've recently (today) started working with GD::Graph. One of the first things I did was to take the sample program from the man page and try and run it. However it won't compile. I've copied it exactly from the man page and have read through man page to see if I could see if it was wrong but it seems ok. Maybe somebody out here can tell me what's wrong.
Heres's my code
use GD::Graph; my @data = ( ["1st","2nd","3rd","4th","5th","6th","7th","8th", "9th"], [ 1, 2, 5, 6, 3, 1.5, 1, 3, 4], [ sort { $a <=> $b } (1, 2, 5, 6, 3, 1.5, 1, 3, 4) ] ); my $graph = GD::Graph::lines->new(400, 300); $graph->set( x_label => 'X Label', y_label => 'Y label', title => 'Some simple graph', y_max_value => 8, y_tick_number => 8, y_label_skip => 2 ); my $gd = my $my_graph->plot(\@data); open(IMG, '>file.gif') or die $!; binmode IMG; print IMG $gd->gif;
And here's the error
Can't locate object method "new" via package "GD::Graph::lines" at first.pl line 12.
