*
* AbstractAreaBase is the base class for all chart elements that have
* a set of background attributes and frame attributes, such as
* legends or axes.
*
* @note Normally you should not use AbstractAreaBase directly, but
* derive your classes from AbstractArea or AbstractAreaWidget.
*
* @note This classis not a QObject, so it is easier to inherit from
* it, if your are inheriting from a QObject too like AbstractAreaWidget does it.
