Detailed Description

template<class T>
class lti::draw2DDistribution< T >

This class draws a 2-D distribution into an image or a channel.

If you want to draw the distribution into an eps picture it is mandatory to specify a size for the eps picture. For example:

  epsdraw<cmykColor> drawer(std::out,point(800,800));

The apply methods draws each point from the given matrices into the given image. It is expected that each row of the matrix represents one point If there is also a vector with ids corresponding to each point in the matrices each id is drawn in an other color or style. First all colors are permuted. (In channels this is only white). After this, if there are more ids than colors available, the style of the points is permuted. If there is no id-vector you can assign a color an the style that will be used. According to the parameter hold the old points that are drawn before are saved. If an instance of this class is used later the old points that were saved will appear to in the image.

Member Function Documentation

template<class T >

bool lti::draw2DDistribution< T >::apply	(	drawBase< T > &	drawer,
		const dmatrix &	dist1,
		const ivector &	ids1,
		const dmatrix &	dist2,
		const ivector &	ids2,
		const bool &	hold = false
	)			const

Draws the points in dist1 and dist2 into an image.

In ids1 and ids2 the ids according to the points in dist1 and dist2 are expected. For each new ID a new style is used. If points in dist1 and dist2 have equal ids, the pionts will be drawn with the same symbol and color, but the symbol will be filled.

Parameters:

	drawer	drawing object that is used.
	dist1	dmatrix with the source data.
	ids1	the ID's accoding to the points in dist
	dist2	dmatrix with the source data.
	ids2	the ID's accoding to the points in dist
	hold	if true the old image is not deleted

Returns:

true if apply successful or false otherwise.

template<class T >

bool lti::draw2DDistribution< T >::apply	(	drawBase< T > &	drawer,
		const dmatrix &	dist,
		const ivector &	ids,
		const bool &	hold = false
	)			const

Draws the points in dist into an image.

For each new ID a new style is used.

Parameters:

	drawer	that drawing object that is used
	dist	dmatrix with the source data.
	ids	the ID's accoding to the points in dist
	hold	if true the old image is not deleted

Returns:

true if apply successful or false otherwise.

template<class T >

bool lti::draw2DDistribution< T >::apply	(	drawBase< T > &	drawer,
		const dvector &	x,
		const dvector &	y,
		const bool	hold = false,
		const char *	style = "ow"
	)			const

Draws the point in the two vectors, taking the first as abscissa and the second as ordinate.

template<class T >

bool lti::draw2DDistribution< T >::apply	(	drawBase< T > &	drawer,
		const dmatrix &	dist,
		const int	first,
		const int	second,
		const bool	hold = false,
		const char *	style = "ow"
	)			const

Draws two dimensions of dist.

See also:

apply(drawer,dist,hold,style)

Parameters:

	drawer	the drawer object used. Usually it is an object of a class inherited from drawBase<T>, like draw<T>.
	dist	dmatrix with the source data.
	first	first dimension taken
	second	second dimension
	hold	if true the old image is not deleted
	style	the style with which the points are drawn

Returns:

true if apply successful or false otherwise.

template<class T >

bool lti::draw2DDistribution< T >::apply	(	drawBase< T > &	drawer,
		const dmatrix &	dist,
		const bool &	hold = false,
		const char *	style = "ow0"
	)			const

Draws the points in dist with the given style into an image.

Parameters:

	drawer	the drawering object that is used.
	dist	dmatrix with the source data.
	hold	if true the old image is not deleted
	style	the style with which the points are drawn

Returns:

true if apply successful or false otherwise.
