Big Faceless Graph Library 2.3.4 (Default branch)
Image The Big Faceless Graph Library is a Java class library for creating graphs and charts. It is backed by a full 3D engine, allowing you to create shaded 3D pie, bar, and line graphs as GIF, PDF, PNG, or other image formats. Its features include transparent backgrounds, extensible axes to graph dates, currencies, custom fonts, and spline curve fitting. It is small, fast, and easy to use. License: Other/Proprietary License with Free Trial Changes:
The FunctionLineSeries has been modified slightly: there is a now a "complete" method for subclasses, and the "setLineSeries" method can retrieve the data from a LineSeries. A matching "series" attribute in the XML has been added. Labels on MultiBar graphs are correctly positioned. NaN values can be used in BoxWhisker series. The Graph Library can now be licensed using a license file.Image

Graph::Writer::XML(3pm) 				User Contributed Perl Documentation				   Graph::Writer::XML(3pm)

NAME

       Graph::Writer::XML - write out directed graph as XML

SYNOPSIS

	   use Graph;
	   use Graph::Writer::XML;

	   $graph = Graph->new();
	   # add edges and nodes to the graph

	   $writer = Graph::Writer::XML->new();
	   $writer->write_graph($graph, 'mygraph.xml');

DESCRIPTION

       Graph::Writer::XML is a class for writing out a directed graph in a simple XML format.  The graph must be an instance of the Graph class,
       which is actually a set of classes developed by Jarkko Hietaniemi.

       The XML format is designed to support the Graph classes: it can be used to represent a single graph with a collection of nodes, and edges
       between those nodes.  The graph, nodes, and edges can all have attributes specified, where an attribute is a (name,value) pair, with the
       value being scalar.

METHODS

   new()
       Constructor - generate a new writer instance.

	   $writer = Graph::Writer::XML->new();

       This doesn't take any arguments.

   write_graph()
       Write a specific graph to a named file:

	   $writer->write_graph($graph, $file);

       The $file argument can either be a filename, or a filehandle for a previously opened file.

KNOWN BUGS

       Attribute values must be scalar. If they're not, well, you're on your own.
