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.

NAME

       Chart::Clicker::Data::Series - A series of key, value pairs representing chart data

VERSION

       version 2.83

SYNOPSIS

	 use Chart::Clicker::Data::Series;

	 my @keys = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10);
	 my @values = (42, 25, 86, 23, 2, 19, 103, 12, 54, 9);

	 my $series = Chart::Clicker::Data::Series->new({
	   keys    => @keys,
	   value   => @values
	 });

	 # Alternately, if you prefer

	 my $series2 = Chart::Clicker::Data::Series->new({
	   1  => 42,
	   2  => 25,
	   3  => 85,
	   4  => 23,
	   5  => 2,
	   6  => 19,
	   7  => 102,
	   8  => 12,
	   9  => 54,
	   10 => 9
	 });

DESCRIPTION

       Chart::Clicker::Data::Series represents a series of values to be charted.

       Despite the name (keys and values) it is expected that all keys and values will be numeric.  Values is pretty obvious, but it is important
       that keys also be numeric, as otherwise we'd have no idea how to order the data.

       If you want to use text labels for your domain's see Chart::Clicker::Axis's tick_labels method.

ATTRIBUTES

   keys
       Set/Get the keys for this series.

   add_to_keys
       Adds a key to this series.

   name
       Set/Get the name for this Series

   range
       Returns the range for this series.

   values
       Set/Get the values for this series.

METHODS

   key_count
       Get the count of keys in this series.

   add_to_values
       Add a value to this series.

   value_count
       Get the count of values in this series.

   add_pair ($key, $value)
       Convenience method to add a single key and a single value to the series.

   get_value_for_key ($key)
       Returns the value associated with the specified key.  This is necessary because not all series will have values for every key.
