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, int  from, int  to  ) 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, QwtPlotIntervalCurve, QwtPlotHistogram, and QwtPlotSpectroCurve.

Qt::Orientation QwtPlotAbstractSeriesItem::orientation

(

)

const

Returns:

Orientation of the plot item

See also:

setOrientation()

void QwtPlotAbstractSeriesItem::setOrientation

(

Qt::Orientation

orientation

)

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.
