In this class the DataInterpreter helper class is used to create a standard interpretation (just y-values). * call applyDefaultStyle() for all XDataSeries in order to apply default styles.

The default implementation is empty. * call createCoordinateSystems() and apply them to the diagram. As default one cartesian system with Scales using a linear Scaling is created. * createChartTypes() is called in order to define the structure of the diagram. For details see comment of this function. As default this method creates a tree where all series appear in one branch with the chart type determined by getChartTypeForNewSeries().
