)

[protected, virtual]

Reimplemented in Updraft::IgcViewer::VerticalSpeedPlotPainter.

[virtual]

virtual void Updraft::IgcViewer::PlotPainter::flushBuffer

(

)

[protected, pure virtual]

Draw points from the buffer.

This method is called every time the graph crosses zero, at the end of the plot and maybe sometimes more.

Implemented in Updraft::IgcViewer::GroundSpeedPlotPainter, Updraft::IgcViewer::VerticalSpeedPlotPainter, and Updraft::IgcViewer::AltitudePlotPainter.

int Updraft::IgcViewer::PlotPainter::getMaxX

void Updraft::IgcViewer::PlotPainter::getRangeAtPixel	(	int	x,
		int *	startIndex,
		int *	endIndex
	)		[virtual]

Returns the index range of the igc info for pixel x.

void Updraft::IgcViewer::PlotPainter::init	(	PlotAxes *	axes,
		FixInfo *	info
