Chart::Clicker::Renderer::Pie(3pm) User Contributed Perl Documentation Chart::Clicker::Renderer::Pie(3pm) NAME
Chart::Clicker::Renderer::Pie - Pie renderer VERSION
version 2.83 SYNOPSIS
my $pier = Chart::Clicker::Renderer::Pie->new; # Optionally set the stroke width $pier->brush->width(2); DESCRIPTION
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). ATTRIBUTES
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. brush Set/Get whether or not the gradient is to be reversed. starting_angle Set/Get a starting angle for the gradient. AUTHOR
