Documentation

I really like the simplicity and usefullness of this collection, but I had a hard time getting it the way I wanted, because of missing documentation. The test files in the distribution were really helpful, but that is not really user-friendly after installation.

use Chart::Points;
my $ch = Chart::Points->new (800, 400);
my @L  = ("unthreaded 1", "unthreaded 2", "threaded 1", "threaded 2");
$ch->set (
    pt_size             => 4,
    legend              => "top",
    legend_labels       => \@L,
    title               => "Issue 21360",
    x_label             => "perl version 5.X.0",
    y_label             => "duration (s)",
    colors              => {
        title           => "blue4",
        background      => [ 240, 240, 240 ],
        dataset0        => [ 191,   0,   0 ],
        dataset1        => [ 127,   0,   0 ],
        dataset2        => [   0, 191,   0 ],
        dataset3        => [   0, 127,   0 ],
        },
    grey_background     => 0,
    );
$ch->png ("x21360.png", [\@l, \@a, \@b, \@A, \@B ]);

Was what I ended up with, where I was most confused about having to use dataset2 instead of e.g. $L[2].

I tried to summerize what I found in the t files:
