int QwtPlotSpectroCurve::rtti ( ) const

virtual

Returns: QwtPlotItem::Rtti_PlotSpectroCurve

Reimplemented from QwtPlotItem.

Definition at line 80 of file qwt_plot_spectrocurve.cpp.

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()

Definition at line 145 of file qwt_plot_spectrocurve.cpp.

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()

Definition at line 174 of file qwt_plot_spectrocurve.cpp.

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()

Definition at line 92 of file qwt_plot_spectrocurve.cpp.

void QwtPlotSpectroCurve::setPenWidth ( double penWidth )

Assign a pen width

Parameters

penWidth New pen width

See also: penWidth()

Definition at line 200 of file qwt_plot_spectrocurve.cpp.

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

Initialize data with an array of samples.

Parameters

samples Vector of points

Definition at line 113 of file qwt_plot_spectrocurve.cpp.

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.

Definition at line 128 of file qwt_plot_spectrocurve.cpp.

bool QwtPlotSpectroCurve::testPaintAttribute ( PaintAttribute attribute ) const

Returns: True, when attribute is enabled

See also: PaintAttribute, setPaintAttribute()
