GLE (Graphics Layout Engine) 4.1.2 (Default branch)
ImageGLE (Graphics Layout Engine) is a graphics scripting language designed for creating publication quality graphs, plots, diagrams, figures, and slides. GLE supports various graph types (including function plots, histograms, bar graphs, scatter plots, contour lines, color maps, and surface plots) through a simple but flexible set of graphing commands. More complex output can be created by relying on GLE's scripting language, which is full featured with subroutines, variables, and logic control. GLE relies on LaTeX for text output and supports mathematical formulae in graphs and figures.License: BSD License (original)Changes:
This release fixes a problem with reading certainJPEG files, one with plotting non-square heightmaps, and one with rotated LaTeX formulas. Itincludes fixes for compilation with GCC 4.3 andhas better support for path names with specialcharacters.Image

NAME

       Graph::Easy::Layout::Force - Force-based layouter for Graph::Easy

SYNOPSIS

	       use Graph::Easy;

	       my $graph = Graph::Easy->new();

	       $graph->add_edge ('Bonn', 'Berlin');
	       $graph->add_edge ('Bonn', 'Ulm');
	       $graph->add_edge ('Ulm', 'Berlin');

	       $graph->layout( type => 'force' );

	       print $graph->as_ascii( );

	       # prints:

	       #   +------------------------+
	       #   |			    v
	       # +------+     +-----+	  +--------+
	       # | Bonn | --> | Ulm | --> | Berlin |
	       # +------+     +-----+	  +--------+

DESCRIPTION

       "Graph::Easy::Layout::Force" contains routines that calculate a force-based layout for a graph.

       Nodes repell each other, while edges connecting them draw them together.

       The layouter calculates the forces on each node, then moves them around according to these forces until things have settled down.

       Used automatically by Graph::Easy.

EXPORT

       Exports nothing.

SEE ALSO

       Graph::Easy.

METHODS

       This module injects the following methods into Graph::Easy:

   _layout_force()
       Calculates the node position with a force-based method.
