NAME
Chart::Clicker::Renderer::Pie - Pie rendererDESCRIPTION
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 $series2's at 33% (1 + 1 + 1 = 3).
SYNOPSIS
my $pier = Chart::Clicker::Renderer::Pie->new; # Optionally set the stroke width $pier->brush->width(2);
ATTRIBUTES
border_color
Set/Get the Color to use for the border.brush
Set/Get a Brush to be used for the pie's border.gradient_color
If supplied, specifies a color to mix with each slice's color for use as a radial gradient. The best results are usually gotten from mixing with a white or black and manipulating the alpha, like so:$ren->gradient_color( 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.
