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.

Member Function Documentation
◆ data() [1/2]
|
inline |
- Returns
- the the series data
Definition at line 146 of file qwt_series_store.h.
◆ data() [2/2]
| const QwtSeriesData< T >* QwtSeriesStore< T >::data | ( | ) | const |
- Returns
- the the series data
◆ dataRect()
|
virtual |
- Returns
- Bounding rectangle of the series or an invalid rectangle, when no series is stored
- See also
- QwtSeriesData<T>::boundingRect()
Implements QwtAbstractSeriesStore.
Definition at line 184 of file qwt_series_store.h.
◆ dataSize()
|
virtual |
- Returns
- Number of samples of the series
- See also

Implements QwtAbstractSeriesStore.
Definition at line 175 of file qwt_series_store.h.
◆ sample()
|
inline |
- Parameters
-
index Index
- Returns
- Sample at position index
Definition at line 158 of file qwt_series_store.h.
◆ setData()
| 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.
Definition at line 164 of file qwt_series_store.h.
◆ setRectOfInterest()
|
virtual |
Set a the "rect of interest" for the series
- Parameters
-
rect Rectangle of interest
Implements QwtAbstractSeriesStore.
Definition at line 193 of file qwt_series_store.h.
◆ swapData()
| QwtSeriesData< T > * QwtSeriesStore< T >::swapData | ( | QwtSeriesData< T > * | series | ) |
Replace a series without deleting the previous one
- Parameters
-
series New series
- Returns
- Previously assigned series
