◆ colorMap()

const QwtColorMap * QwtPlotSpectroCurve::colorMap ( ) const

Get the color map

Get the color map used for mapping intensity values to colors

返回: Color map used for mapping the intensity values to colors

参见: setColorMap(), setColorRange(), QwtColorMap::color()

◆ colorRange()

const QwtInterval & QwtPlotSpectroCurve::colorRange ( ) const

Get the color range

Get the value interval that corresponds to the color map

返回: Value interval that corresponds to the color map

参见: setColorRange(), setColorMap(), QwtColorMap::color()

◆ drawDots()

		const QwtScaleMap &	xMap,
		const QwtScaleMap &	yMap,
		const QRectF &	canvasRect,
		int	from,
		int	to
	)		const

protectedvirtual

Draw the dots

Draw a subset of the points

参数

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.

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

参见: drawDots()

实现了 QwtPlotSeriesItem.

◆ penWidth()

double QwtPlotSpectroCurve::penWidth ( ) const

Get the pen width

Get the pen width used to draw a dot

返回: Pen width used to draw a dot

参见: setPenWidth()

◆ rtti()

int QwtPlotSpectroCurve::rtti ( ) const

overridevirtual

Get the runtime type information

返回: QwtPlotItem::Rtti_PlotSpectroCurve

重载 QwtPlotItem .

◆ setColorMap()

void QwtPlotSpectroCurve::setColorMap ( QwtColorMap * colorMap )

Set the color map

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.

参数

[in] colorMap Color map

参见: colorMap(), setColorRange(), QwtColorMap::color(), QwtScaleWidget::setColorBarEnabled(), QwtScaleWidget::setColorMap()

◆ setColorRange()

void QwtPlotSpectroCurve::setColorRange ( const QwtInterval & interval )

Set the color range

Set the value interval that corresponds to the color map

参数

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

参见: colorRange(), setColorMap(), QwtColorMap::color()

◆ setPaintAttribute()

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

Set a paint attribute

Specify an attribute how to draw the curve

参数

[in]	attribute	Paint attribute
[in]	on	On/Off

参见: PaintAttribute, testPaintAttribute()

◆ setPenWidth()

void QwtPlotSpectroCurve::setPenWidth ( double penWidth )

Set the pen width

Assign a pen width

参数

[in] penWidth New pen width

参见: penWidth()

◆ setSamples() [1/2]

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

Set the samples

Initialize data with an array of samples

参数

[in] samples Vector of points

◆ setSamples() [2/2]

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

Set the samples

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.

参数

[in] data Data

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

◆ testPaintAttribute()

bool QwtPlotSpectroCurve::testPaintAttribute ( PaintAttribute attribute ) const

Test a paint attribute

Test if a paint attribute is enabled

返回: True when attribute is enabled

参见: PaintAttribute, setPaintAttribute()
