virtual bool casa::PlotPointData::minsMaxes	(	double &	xMin,
		double &	xMax,
		double &	yMin,
		double &	yMax
	)

pure virtual

Gets the minimum and maximum values.

Returns false for error.

Implemented in casa::PlotHistogramData, casa::PlotPointDataImpl< T >, and casa::PlotMSIndexer.

virtual unsigned int casa::PlotPointData::size ( ) const

pure virtual

ABSTRACT METHODS //.

Returns the number of points.

Implemented in casa::PlotHistogramData, casa::PlotPointDataImpl< T >, and casa::PlotMSIndexer.

virtual void casa::PlotPointData::xAndYAt	(	unsigned int	index,
		double &	x,
		double &	y
	)		const

virtual

IMPLEMENTED METHODS //.

Gets the x and y values at the given index. Default implementation just calls xAt and yAt, but in subclasses where performance could be gained, this method should be overridden. Implementations for plots that use PlotPointData should use this method by default in case there are performance gains.

Reimplemented in casa::PlotMSRaDecIndexer, and casa::PlotMSIndexer.

virtual double casa::PlotPointData::xAt ( unsigned int i ) const

pure virtual

Returns the x value at the given index.

Implemented in casa::PlotHistogramData, casa::PlotPointDataImpl< T >, casa::PlotMSRaDecIndexer, and casa::PlotMSIndexer.

virtual double casa::PlotPointData::yAt ( unsigned int i ) const

pure virtual

Returns the y value at the given index.

Implemented in casa::PlotHistogramData, casa::PlotPointDataImpl< T >, casa::PlotMSRaDecIndexer, and casa::PlotMSIndexer.
