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.

  template<typename T > QwtSeriesData< T > * QwtSeriesStore< T >::data () [inline]

Returns
    the the series data

  template<typename T > const QwtSeriesData< T > * QwtSeriesStore< T >::data () const [inline]

Returns
    the the series data

  template<typename T > QRectF QwtSeriesStore< T >::dataRect () const [virtual]

Returns
    Bounding rectangle of the series or an invalid rectangle, when no series is stored

See also
    QwtSeriesData<T>::boundingRect()

Implements QwtAbstractSeriesStore.

  template<typename T > size_t QwtSeriesStore< T >::dataSize () const [virtual]

Returns
    Number of samples of the series

See also
    setData(), QwtSeriesData<T>::size()

Implements QwtAbstractSeriesStore.

  template<typename T > T QwtSeriesStore< T >::sample (int index) const [inline]

Parameters
    index Index

Returns
    Sample at position index

  template<typename T> void QwtSeriesStore< T >::setData (QwtSeriesData< T > * series)
Assign a series of samples

Parameters
    series Data

Warning
    The item takes ownership of the data object, deleting it when its not used anymore.

  template<typename T > void QwtSeriesStore< T >::setRectOfInterest (const QRectF & rect) [virtual]
Set a the 'rect of interest' for the series

Parameters
    rect Rectangle of interest

See also
    QwtSeriesData<T>::setRectOfInterest()

Implements QwtAbstractSeriesStore.

  template<typename T> QwtSeriesData< T > * QwtSeriesStore< T >::swapData (QwtSeriesData< T > * series)
Replace a series without deleting the previous one

Parameters
    series New series

Returns
    Previously assigned series
