Detailed Description

template<typename T>
class QwtSeriesStore< T >

Class storing a QwtSeriesData object.

QwtSeriesStore and QwtPlotSeriesItem are intended as base classes for all plot items iterating over a series of samples. Both classes share a virtual base class ( QwtAbstractSeriesStore ) to bridge between them.

QwtSeriesStore offers the template based part for the plot item API, so that QwtPlotSeriesItem can be derived without any hassle with templates.
