Constructor & Destructor Documentation

EqPotGraph::EqPotGraph	(	const MeshScalarField &	epot,
		const Geometry &	geom
	)

Constructor for equipotential line plot.

Makes a plot object for plotting equipotential data from scalarfield field in geometry g.

EqPotGraph::~EqPotGraph ( )

virtual

Destructor,.

Member Function Documentation

void EqPotGraph::disable_cache

(

void

)

Disable internal cache.

Makes equipotential lines to be calculated at every plot().

void EqPotGraph::get_bbox ( double  bbox[4] )

virtual

Get bounding box of drawable.

Returns the bounding box of the drawable in array bbox in order xmin, ymin, xmax, ymax.

Implements Graph3D.

void EqPotGraph::plot ( cairo_t *  cairo, const Coordmapper *  cm, const double  range[4]  )

virtual

Plot graph with cairo.

Plot the graph using cairo and coordinate mapper cm. The visible range of plot is given in array range in order xmin, ymin, xmax, ymax. The graph should be able to handle any range values. Also min > max.

Called by Frame during drawing.

Implements Graph3D.

void EqPotGraph::plot_sample ( cairo_t *  cairo, double  x, double  y, double  width, double  height  )

virtual

Plot sample for legend.

Plot graph sample for legend at cairo coordinates (x,y).

Implements Graph3D.

void EqPotGraph::set_eqlines_auto

(

size_t

N

)

Set N automatic equipotential lines to be plotted between minimum potential and maximum potentials.

void EqPotGraph::set_eqlines_manual

(

const std::vector< double > &

pot

)

Add manual equipotential lines to be plotted at specified potentials.
