Detailed Description
Bridge between QwtSeriesStore and QwtPlotSeriesItem.
QwtAbstractSeriesStore is an abstract interface only to make it possible to isolate the template based methods ( QwtSeriesStore ) from the regular methods ( QwtPlotSeriesItem ) to make it possible to derive from QwtPlotSeriesItem without any hassle with templates.
