VERSION
version 2.83
SYNOPSIS
use Chart::Clicker::Data::Series::HighLow;
my @keys = ();
my @values = ();
my @highs = ();
my @lows = ();
my @opens = ();
my $series = Chart::Clicker::Data::Series::HighLow->new({

lows => @lows,
opens => @opens
});
DESCRIPTION
Chart::Clicker::Data::Series::HighLow is an extension of the Series class that provides storage for a three new variables called for use

- <-- max of Open, Value
| |
| |
- <-- min of Open, Value
|
|
--- <-- Low

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.
