Constructor & Destructor Documentation

mimas::gnuplot::gnuplot	(	image< rgba< unsigned char > > &	_img,
		int	_width,
		int	_height,
		int	_timeout = `3`
	)			throw (mimasexception)

Constructor.

virtual mimas::gnuplot::~gnuplot ( void ) [virtual]

Destructor.

Will call finish(), if it was not called already.

Member Function Documentation

void mimas::gnuplot::finish ( void ) throw (mimasexception)

Render plot to image.

std::string mimas::gnuplot::getScript ( void ) const [inline]

Get current script.

You can request the script at it's current state (without the terminal-command).

template<typename T>

std::ostream& mimas::gnuplot::operator<< ( const T & t ) [inline]

Append something to the gnuplot script.

Definition at line 34 of file gnuplot.h.

References program.

std::ostream& mimas::gnuplot::operator<< ( std::ostream &(*)(std::ostream &) __pf ) [inline]

Append io-manipulator to the gnuplot script.

Definition at line 36 of file gnuplot.h.

References program.

template<typename T>

void mimas::gnuplot::plot ( const boost::numeric::ublas::vector< T > & vec )

Plot vector - like in Octave.

Definition at line 153 of file gnuplot.h.

template<typename T>

void mimas::gnuplot::plot ( const boost::numeric::ublas::matrix< T > & mat )

Plot matrix - like in Octave.

Definition at line 163 of file gnuplot.h.

template<typename T>

void mimas::gnuplot::plot	(	const boost::numeric::ublas::matrix< T > &	mat,
		int	xcol,
		int	ycol,
		const std::string &	style = `"points"`,
		int	type = `1`,
		int	size = `1`
	)			throw (mimasexception)

Plotting of xcol against ycol.

Columns are indexed from 0. style is either "line" or "point". type is an integer which specifies the type of line or point (refer to gnuplot package). size is the point or line size. Use setMultiPlot to overlay plots.
