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.
