	GSVG (size_t width, size_t height, size_t hWindows=1, size_t vWindows=1)
	This object represents a hWindows-by-vWindows grid of charts. Typically, hWindows and vWindows are 1, so this is just a single chart, but you may specify larger values to produce a grid of charts. width and height specify the width and height of the entire grid of charts. An equal portion of the width and height is given to each chart in the grid. More...

	~GSVG ()

void	add_raw (const char *string)
	Writes some raw SVG code to the stream. More...

void	clip ()
	After calling this method, all draw operations will be clipped to fall within (xmin, ymin)-(xmax, ymax), until a new chart is started. More...

void	dot (double x, double y, double r=1.0, unsigned int col=0x000080)
	Draw a dot. More...

double	horizLabelPos ()
	Returns a good y position for the horizontal axis label. More...

void	horizMarks (int maxLabels, bool notext=false, std::vector< std::string > *pLabels=NULL)
	Label the horizontal axis. If maxLabels is 0, then no grid-lines will be drawn. If maxLabels is -1, then Logarithmic grid-lines will be drawn. If pLabels is non-NULL, then its values will be used to label the grid-lines instead of the continuous values. More...

double	hunit ()
	Returns (xmax - xmin) / width, which is often a useful size. More...

void	line (double x1, double y1, double x2, double y2, double thickness=1.0, unsigned int col=0x008000)
	Draw a line. More...

void	newChart (double xmin, double ymin, double xmax, double ymax, size_t hPos=0, size_t vPos=0, double margin=100)
	Start a new chart. This method must be called before any drawing operations are performed. xmin, ymin, xmax, and ymax specify the coordinates in the chart to begin drawing. If this contains more than a 1x1 grid of charts, then you may call this method again to begin drawing a different chart in the grid. hPos and vPos specify which chart in the grid to begin drawing. More...

void	print (std::ostream &stream)
	Generate an SVG file with all of the components that have been added so far. More...

void	rect (double x, double y, double w, double h, unsigned int col=0x008080)
	Draw a rectangle. More...

void	text (double x, double y, const char *szText, double size=1.0, Anchor eAnchor=Start, unsigned int col=0x000000, double angle=0.0, bool serifs=true)
	Draw text. More...

double	vertLabelPos ()
	Returns a good x position for the vertical axis label. More...

void	vertMarks (int maxLabels, bool notext=false, std::vector< std::string > *pLabels=NULL)
	Label the vertical axis. If maxLabels is 0, then no grid-lines will be drawn. If maxLabels is -1, then Logarithmic grid-lines will be drawn. If pLabels is non-NULL, then its values will be used to label the grid-lines instead of the continuous values. More...

	Returns (ymax - ymin) / height, which is often a useful size. More...

GClasses::GSVG::GSVG	(	size_t	width,
		size_t	height,
		size_t	hWindows = `1`,
		size_t	vWindows = `1`
	)

This object represents a hWindows-by-vWindows grid of charts. Typically, hWindows and vWindows are 1, so this is just a single chart, but you may specify larger values to produce a grid of charts. width and height specify the width and height of the entire grid of charts. An equal portion of the width and height is given to each chart in the grid.

void GClasses::GSVG::add_raw ( const char * string )

Writes some raw SVG code to the stream.

void GClasses::GSVG::clip ( )

After calling this method, all draw operations will be clipped to fall within (xmin, ymin)-(xmax, ymax), until a new chart is started.

void GClasses::GSVG::color ( unsigned int c )

protected

void GClasses::GSVG::dot	(	double	x,
		double	y,

void GClasses::GSVG::horizMarks	(	int	maxLabels,
		bool	notext = `false`,
		std::vector< std::string > *	pLabels = `NULL`
	)

Label the horizontal axis. If maxLabels is 0, then no grid-lines will be drawn. If maxLabels is -1, then Logarithmic grid-lines will be drawn. If pLabels is non-NULL, then its values will be used to label the grid-lines instead of the continuous values.

double GClasses::GSVG::hunit ( )

		std::vector< std::string > *	pLabels = `NULL`
	)

Label the vertical axis. If maxLabels is 0, then no grid-lines will be drawn. If maxLabels is -1, then Logarithmic grid-lines will be drawn. If pLabels is non-NULL, then its values will be used to label the grid-lines instead of the continuous values.
