Detailed Description

This is the QwtRasterData for a scatter plot.

This gives Qwt values to put in each bin for a spectrogram, effectively making the scatter plot.

Isis::ScatterPlotData::ScatterPlotData ( const ScatterPlotData & other )

This is an optimized copy constructor.

Copies are not zero-time, but they are pretty quick.

Parameters

other The ScatterPlotData to copy.

Isis::ScatterPlotData::~ScatterPlotData ( )

Destructor.

This is for viewport->plot alarming.

Parameters

x	The x-dn value of the bin to alarm
y	The y-dn value of the bin to alarm

Get the count (number of values) which fall into the bin at index.

Parameters

binIndex The bin we're getting the data from

Returns: The total number of cube DNs which fall into the given bin

ScatterPlotData & Isis::ScatterPlotData::operator= ( const ScatterPlotData & other )

Take the data from other and copy it into this.

This uses the copy-and-swap paradigm for exception safety.

Parameters

QRectF Isis::ScatterPlotData::pixelHint ( const QRectF & area ) const

This is a hint given to qwt for how to render a pixel in the spectrogram.

Parameters

area	This is ignored

Returns: The size of a pixel in the scatter plot

void Isis::ScatterPlotData::swap ( ScatterPlotData & other )

This is part of the copy-and-swap paradigm.

Swap member data with other.

Parameters

	)		const

virtual

This gets called every time the scatter plot is re-drawn.

This returns the counts for each DN (x), DN (y), or if the bin is alarmed this returns the max count.

Parameters

x	The X-Dn value
y	The Y-Dn value

Returns: The bin's colorizable-value
