Manual Reference Pages - CHART::CLICKER::RENDERER::PIE (3)
Chart::Clicker::Renderer::Pie - Pie renderer
my $pier = Chart::Clicker::Renderer::Pie->new;
# Optionally set the stroke width
Chart::Clicker::Renderer::Pie renders a dataset as slices of a pie. The keys
of like-named Series are totaled and keys are ignored. So for a dataset like:
my $series = Chart::Clicker::Data::Series->new(
keys => [ 1, 2, 3 ],
values => [ 1, 2, 3],
my $series2 = Chart::Clicker::Data::Series->new(
keys => [ 1, 2, 3],
values => [ 1, 1, 1 ],
The keys are discarded and a pie chart will be drawn with $series slice at
66% (1 + 2 + 3 = 6) and $series2s at 33% (1 + 1 + 1 = 3).
Set/Get the color to use for the border.
Set/Get a brush to be used for the pies border.
If supplied, specifies a color to mix with each slices color for use as a
radial gradient. The best results are usually gotten from mixing with a
white or black and manipulating the alpha, like so:
Graphics::Color::RGB->new(red => 1, green => 1, blue => 1, alpha => .3)
The above will cause each generated color to fade toward a lighter version of
itself. Adjust the alpha to increase or decrease the effect.
Set/Get whether or not the gradient is to be reversed.
Set/Get a starting angle for the gradient.
