#include <KDChartAbstractAreaBase.h>
Inheritance diagram for KDChart::AbstractAreaBase:
AbstractAreaBase is the base class for all chart elements that have a set of background attributes and frame attributes, such as legends or axes.
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.
