Detailed Description

Abstract base class for drawable plots.

Graph type objects are used in Frame type plots to provide the graphical view of the data content and legend sample.

Constructor & Destructor Documentation

~Graph()

virtual Graph::~Graph ( )

inlinevirtual

Virtual destructor.

Member Function Documentation

get_bbox()

virtual void Graph::get_bbox ( double  bbox[4] )

pure virtual

Get bounding box of graph.

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

Implemented in Graph3D, XYGraph, SolidGraph, ParticleGraph, MeshGraph, MeshColormap, FieldGraph, and EqPotGraph.

plot()

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

pure 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.

Implemented in Graph3D, XYGraph, SolidGraph, ParticleGraph, MeshGraph, MeshColormap, FieldGraph, and EqPotGraph.

plot_sample()

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

pure virtual

Plot sample for legend.

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

Implemented in Graph3D, XYGraph, SolidGraph, ParticleGraph, MeshGraph, MeshColormap, FieldGraph, and EqPotGraph.
