Detailed Description

DotWriter is a helper class for writing graphviz .dot files.

Inheritance diagram for gtsam::DotWriter:

Public Member Functions
	DotWriter (double figureWidthInches=5, double figureHeightInches=5, bool plotFactorPoints=true, bool connectKeysToFactor=true, bool binaryEdges=false)
void	graphPreamble (std::ostream *os) const
	Write out preamble for graph, including size.
void	digraphPreamble (std::ostream *os) const
	Write out preamble for digraph, including size.
void	drawVariable (Key key, const KeyFormatter &keyFormatter, const std::optional< Vector2 > &position, std::ostream *os) const
	Create a variable dot fragment.
std::optional< Vector2 >	variablePos (Key key) const
	Return variable position or none.
void	processFactor (size_t i, const KeyVector &keys, const KeyFormatter &keyFormatter, const std::optional< Vector2 > &position, std::ostream *os) const
	Draw a single factor, specified by its index i and its variable keys.

Static Public Member Functions
static void	DrawFactor (size_t i, const std::optional< Vector2 > &position, std::ostream *os)
	Create factor dot.

Public Attributes
double	figureWidthInches
	The figure width on paper in inches.
double	figureHeightInches
	The figure height on paper in inches.
bool	plotFactorPoints
	Plots each factor as a dot between the variables.
bool	connectKeysToFactor
	Draw a line from each key within a factor to the dot of the factor.
bool	binaryEdges
	just use non-dotted edges for binary factors
std::map< Key, Vector2 >	variablePositions
	Variable positions can be optionally specified and will be included in the dot file with a "!' sign, so "neato" can use it to render them.
std::map< char, double >	positionHints
	The position hints allow one to use symbol character and index to specify position.
KeySet	boxes
	A set of keys that will be displayed as a box.
std::map< size_t, Vector2 >	factorPositions
	Factor positions can be optionally specified and will be included in the dot file with a "!' sign, so "neato" can use it to render them.

std::map<char, double> gtsam::DotWriter::positionHints

The position hints allow one to use symbol character and index to specify position.

Unless variable positions are specified, if a hint is present for a given symbol, it will be used to calculate the positions as (index,hint).
