QwtPlotAbstractSeriesItem - Base class for plot items representing a series of samples. SYNOPSIS
#include <qwt_plot_seriesitem.h> Inherits QwtPlotItem. Inherited by QwtPlotSeriesItem< T >, QwtPlotSeriesItem< QPointF >, QwtPlotSeriesItem< QwtIntervalSample >, and QwtPlotSeriesItem< QwtPoint3D >.

Member Function Documentation void QwtPlotAbstractSeriesItem::draw (QPainter *painter, const QwtScaleMap &xMap, const QwtScaleMap &yMap, const QRectF &canvasRect) const [virtual] Draw the complete series. Parameters: painter Painter xMap Maps x-values into pixel coordinates. yMap Maps y-values into pixel coordinates. canvasRect Contents rect of the canvas Implements QwtPlotItem. virtual void QwtPlotAbstractSeriesItem::drawSeries (QPainter *painter, const QwtScaleMap &xMap, const QwtScaleMap &yMap, const QRectF &canvasRect, intfrom, intto) const [pure virtual] Draw a subset of the samples Parameters: painter Painter xMap Maps x-values into pixel coordinates. yMap Maps y-values into pixel coordinates. canvasRect Contents rect of the canvas from Index of the first point to be painted to Index of the last point to be painted. If to < 0 the curve will be painted to its last point. Implemented in QwtPlotCurve, QwtPlotHistogram, QwtPlotIntervalCurve, and QwtPlotSpectroCurve. Qt::Orientation QwtPlotAbstractSeriesItem::orientation () const Returns: Orientation of the plot item See also: setOrientation() void QwtPlotAbstractSeriesItem::setOrientation (Qt::Orientationorientation) Set the orientation of the item. The orientation() might be used in specific way by a plot item. F.e. a QwtPlotCurve uses it to identify how to display the curve int QwtPlotCurve::Steps or QwtPlotCurve::Sticks style.
