Detailed Description¶
template<typename T> class QwtPlotSeriesItem< T >¶
Class template for plot items representing a series of samples.Constructor & Destructor Documentation¶
template<typename T > QwtPlotSeriesItem< T >::QwtPlotSeriesItem (const QString &title = QString::null) [explicit] Constructor¶
Parameters:title Title of the series item
template<typename T > QwtPlotSeriesItem< T >::QwtPlotSeriesItem (const QwtText &title) [explicit] Constructor¶
Parameters:title Title of the series item
template<typename T > QwtPlotSeriesItem< T >::~ QwtPlotSeriesItem () [virtual]¶
Destructor.Member Function Documentation¶
template<typename T > QRectF QwtPlotSeriesItem< T >::boundingRect () const [virtual] Returns:¶
Bounding rectangle of the data. If there is no
bounding rect, like for empty data the rectangle is invalid.

template<typename T > QwtSeriesData< T > * QwtPlotSeriesItem< T >::data () [inline] Returns:¶
the the curve data
template<typename T > const QwtSeriesData< T > * QwtPlotSeriesItem< T >::data () const [inline] Returns:¶
the the curve data
template<typename T > size_t QwtPlotSeriesItem< T >::dataSize () const Return the size of the data arrays¶
See also:setData()
template<typename T > T QwtPlotSeriesItem< T >::sample (intindex) const [inline] Parameters:¶
index Index
Returns:
Sample at position index
template<typename T> void QwtPlotSeriesItem< T >::setData ( QwtSeriesData< T > *data) Assign a series of samples¶
Parameters:data Data
Warning:
The item takes ownership of the data object,
deleting it when its not used anymore.
template<typename T > void QwtPlotSeriesItem< T >::updateScaleDiv (const QwtScaleDiv &xScaleDiv, const QwtScaleDiv &yScaleDiv) [virtual] Update the rect of interest according to the current scale ranges¶
Parameters:xScaleDiv Scale division of the x-axis
yScaleDiv Scale division of the y-axis
