Member Function Documentation

const QwtColorMap * QwtPlotSpectroCurve::colorMap ( ) const

Returns: Color Map used for mapping the intensity values to colors

See Also: setColorMap(), setColorRange(), QwtColorMap::color()

QwtInterval & QwtPlotSpectroCurve::colorRange ( ) const

Returns: Value interval, that corresponds to the color map

See Also: setColorRange(), setColorMap(), QwtColorMap::color()

		const QRectF &	canvasRect,
		int	from,
		int	to
	)		const

protectedvirtual

Draw a subset of the points

Parameters

painter	Painter
xMap	Maps x-values into pixel coordinates.
yMap	Maps y-values into pixel coordinates.
canvasRect	Contents rectangle of the canvas
from	Index of the first sample to be painted
to	Index of the last sample to be painted. If to < 0 the series will be painted to its last sample.

Draw a subset of the points

Parameters

painter	Painter
xMap	Maps x-values into pixel coordinates.
yMap	Maps y-values into pixel coordinates.
canvasRect	Contents rectangle of the canvas
from	Index of the first sample to be painted
to	Index of the last sample to be painted. If to < 0 the series will be painted to its last sample.

See Also: drawDots()

Implements QwtPlotSeriesItem.

double QwtPlotSpectroCurve::penWidth ( ) const

Returns: Pen width used to draw a dot

See Also: setPenWidth()

int QwtPlotSpectroCurve::rtti ( ) const

virtual

Returns: QwtPlotItem::Rtti_PlotSpectroCurve

Reimplemented from QwtPlotItem.

void QwtPlotSpectroCurve::setColorMap ( QwtColorMap * colorMap )

Change the color map

Often it is useful to display the mapping between intensities and colors as an additional plot axis, showing a color bar.

Parameters

colorMap Color Map

See Also: colorMap(), setColorRange(), QwtColorMap::color(), QwtScaleWidget::setColorBarEnabled(), QwtScaleWidget::setColorMap()

void QwtPlotSpectroCurve::setColorRange ( const QwtInterval & interval )

Set the value interval, that corresponds to the color map

Parameters

interval interval.minValue() corresponds to 0.0, interval.maxValue() to 1.0 on the color map.

See Also: colorRange(), setColorMap(), QwtColorMap::color()

void QwtPlotSpectroCurve::setPaintAttribute	(	PaintAttribute	attribute,
		bool	on = `true`
	)

Specify an attribute how to draw the curve

Parameters

attribute	Paint attribute
on	On/Off /sa PaintAttribute, testPaintAttribute()

void QwtPlotSpectroCurve::setPenWidth ( double penWidth )

Assign a pen width

Parameters

penWidth New pen width

See Also: penWidth()

void QwtPlotSpectroCurve::setSamples ( const QVector< QwtPoint3D > & samples )

Initialize data with an array of samples.

Parameters

samples Vector of points

void QwtPlotSpectroCurve::setSamples ( QwtSeriesData< QwtPoint3D > * data )

Assign a series of samples

setSamples() is just a wrapper for setData() without any additional value - beside that it is easier to find for the developer.

Parameters

data Data

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

bool QwtPlotSpectroCurve::testPaintAttribute ( PaintAttribute attribute ) const

Returns: True, when attribute is enabled
