NAME

Chart::GGPlot::Theme::ElementTree - Definitions of theme elements

VERSION

version 0.0005

DESCRIPTION

An element tree is a specification of a set of elements usable by themes in the Chart::GGPlot system. For each element its value type is defined. Also an elment can inherit other elements, so that in case of an absent element Chart::GGPlot knows to look for values from its parent elements.

A consumer of Chart::GGPlot::Theme shall follow the element tree and specify values to elements. A Chart::GGPlot::Backend consumer, depend on its implementation, shall support (at least a subset of) theme elements defined in the element tree.

This module provides a default element tree, and normally you do not need to define your own element tree.
