Detailed Description

Abstract base class for geometry slice plots.

Implementation of Graph. Used in Frame type plots.

Provides functionality to select a slice of geometry along axes at any mesh level in any direction. The direction is selected with view and level in integer (mesh count) level. Provides the child class with permutated coordinate indexes. The first coordinate (index vb[0]) will be used for the horizontal axis of the plot, the second coordinate (index vb[1]) for the vertical axis and the third coordinate (index vb[2]) for the level. In three dimensions all the views are possible. In two dimensions, only VIEW_XY and VIEW_YX are possible. Here there is no separate redial index, Y is used instead.

Member Function Documentation

get_bbox()

virtual void Graph3D::get_bbox ( double  bbox[4] )

pure virtual

Get bounding box of drawable.

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

Implements Graph.

Implemented in SolidGraph, ParticleGraph, MeshGraph, FieldGraph, and EqPotGraph.

plot()

virtual void Graph3D::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.

Implements Graph.

Implemented in SolidGraph, ParticleGraph, MeshGraph, FieldGraph, and EqPotGraph.

plot_sample()

virtual void Graph3D::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).

Implements Graph.

Implemented in SolidGraph, ParticleGraph, MeshGraph, FieldGraph, and EqPotGraph.

set_view()

void Graph3D::set_view ( view_e  view, int  level  )

inline

Set the view of 3D drawable.

Sets view direction to view and the view level to level.
