I can get both "func" and "points" to create a plot file under Linux, but in Windows the "points" output file is empty while the "func" output file looks right. Uncomment the "func" line and comment the points line. I included the "gnuplot" path for Windows. Here is my test code: 
#!/usr/bin/perl

use warnings;
use Chart::Gnuplot;

my $chart = Chart::Gnuplot->new(
     gnuplot => 'e:\apps\gnuplot\bin\wgnuplot.exe',
     output => 'testfile.gif',
     terminal => "gif transparent",
);

my @xy = (
    [1.1, -3],
    [1.2, -2],
    [3.5, 0]
);

my $dataSet = Chart::Gnuplot::DataSet->new(
    points => \@xy
#    func => "20*sin(x)"
);

$chart->plot2d($dataSet);

Also, is there a way to find out if gnuplot is complaining about something through Chart::Gnuplot ?
