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
colorMapColor Map

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
intervalinterval.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
attributePaint attribute
onOn/Off /sa PaintAttribute, testPaintAttribute()

Definition at line 92 of file qwt_plot_spectrocurve.cpp.

void QwtPlotSpectroCurve::setPenWidth ( double  penWidth)

Assign a pen width

Parameters
penWidthNew 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
samplesVector 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
dataData
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()
