Renderer for displaying XY data as histograms.

Constructor & Destructor Documentation

XYHistoRenderer::XYHistoRenderer	(	int	barWidth = 10,
		bool	vertical = true
	)

Constructs new XYHistoRenderer.

Parameters

barWidth	width to histogram bars
vertical	true to draw vertical bars, false - to horizontal

Member Function Documentation

void XYHistoRenderer::Draw ( wxDC &  dc, wxRect  rc, Axis *  horizAxis, Axis *  vertAxis, XYDataset *  dataset  )

virtual

Draws dataset.

Parameters

dc	device context
rc	rectangle where to draw
horizAxis	horizontal axis
vertAxis	vertical axis
dataset	dataset to be drawn

Implements XYRenderer.
