Member Function Documentation

Returns:
Color Map used for mapping the intensity values to colors
See also:
setColorMap(), setColorRange(), QwtColorMap::color()

Definition at line 161 of file qwt_plot_spectrocurve.cpp.

Returns:
Value interval, that corresponds to the color map
See also:

Definition at line 189 of file qwt_plot_spectrocurve.cpp.

void QwtPlotSpectroCurve::drawDots ( QPainter *  painter,
const QwtScaleMap xMap,
const QwtScaleMap yMap,
const QRectF &  canvasRect,
int  from,
int  to 
) const [protected, virtual]

Draw a subset of the points

Parameters:
painterPainter
xMapMaps x-values into pixel coordinates.
yMapMaps y-values into pixel coordinates.
canvasRectContents rectangle of the canvas
fromIndex of the first sample to be painted
toIndex of the last sample to be painted. If to < 0 the series will be painted to its last sample.

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

Draw a subset of the points

Parameters:
painterPainter
xMapMaps x-values into pixel coordinates.
yMapMaps y-values into pixel coordinates.
canvasRectContents rectangle of the canvas
fromIndex of the first sample to be painted
toIndex of the last sample to be painted. If to < 0 the series will be painted to its last sample.

Implements QwtPlotSeriesItem.

Definition at line 236 of file qwt_plot_spectrocurve.cpp.

void QwtPlotSpectroCurve::init ( ) [private]

Initialize data members.

Definition at line 68 of file qwt_plot_spectrocurve.cpp.

Returns:
Pen width used to draw a dot
See also:
setPenWidth()

Definition at line 218 of file qwt_plot_spectrocurve.cpp.

int QwtPlotSpectroCurve::rtti ( ) const [virtual]
Returns:
QwtPlotItem::Rtti_PlotSpectroCurve

Reimplemented from QwtPlotItem.

Definition at line 80 of file qwt_plot_spectrocurve.cpp.

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
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:
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.

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.

Returns:
True, when attribute is enabled
See also:
PaintAttribute, setPaintAttribute()

Definition at line 104 of file qwt_plot_spectrocurve.cpp.
