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.

Returns:

the the series data

Returns:

the the series data

Returns:

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

See also:

QwtSeriesData<T>::boundingRect()

Implements QwtAbstractSeriesStore.

Returns:

Number of samples of the series

See also:

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

Implements QwtAbstractSeriesStore.

Parameters:

index Index

Returns:

Sample at position index

Assign a series of samples

Parameters:

series Data

Warning:

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

Set a the 'rect of interest' for the series

Parameters:

rect Rectangle of interest

QwtSeriesData<T>::setRectOfInterest()

Implements QwtAbstractSeriesStore.

Replace a series without deleting the previous one

Parameters:

series New series

Returns:

Previously assigned series
