DESCRIPTION

This class represents a pie chart. A pie chart displays a single dataset as a set of pie slices.

ATTRIBUTES

This class is a subclass of Chart::OFC and accepts all of that class's attribute. It has several attributes of its own which may be passed to the new() method.

dataset

This should be a single dataset of the Chart::OFC::Dataset class. (It could be any Dataset subclass, but all the subclass's attributes will be ignored).

This attribute is required.

slice_colors

This should an array of colors. If you give fewer colors than there are in your dataset then colors will be reused (in order).

This defaults to "red, blue, green, yellow, orange, purple, black".

line_color

The colors of the lines which define slices.

Defaults to #000000 (black).

labels

This should be an array reference containing one or more labels for the slices. This should contain one label per valuable in the dataset.

label_style

A snippet of CSS that will be applied to the labels. The default is "color: #000000". If you change this you should probably make sure to include a color.

opacity

This defines how opaque the slices are. When they are moused over, they become fully opaque.

Defaults to 80 (percent).

ROLES

This class does the Chart::OFC::Role::OFCDataLines role.
