GD::Graph is a *perl5* module to create charts using the GD module. The following classes for graphs with axes are defined: "GD::Graph::lines" Create a line chart. "GD::Graph::bars" and "GD::Graph::hbars" Create a bar chart with vertical or horizonta...

This is a *perl5* module to generate HTML map text for following GD::Graph objects GD::Graph::pie, GD::Graph::bars, GD::Graph::lines, GD::Graph::area, GD::Graph::point and GD::Graph::linespoints. As a result of its work is created HTML code containin...

This module encapsulates the data structure that is needed for GD::Graph and friends. An object of this class contains a list of X values, and a number of lists of corresponding Y values. This only really makes sense if the Y values are numerical, bu...

This package is a wrapper arround GD to produce polar graphs with an easy interface. I use this package to display GPS satellites on a graph with data from the Net::GPSD3 package....

This class is a parent for all GD::Graph classes, including GD::Graph::Data, and offers error and warning handling and some debugging control. Errors are stored in a lexical hash in this package, so the implementation of the subclass should be irrele...

This is a wrapper module which is completely identical to creating a GD::Graph::bars object with the "rotate_chart" attribute set to a true value....

The GD::Graph::colour package provides a few routines to work with colours. The functionality of this package is mainly defined by what is needed, now and historically, by the GD::Graph modules....

The primary purpose of this module is to allow a very easy to use, lightweight and fast charting capability for static pages, dynamic pages and CGI scripts, with the chart creation process abstracted and placed on any server. For example, embedding a...

A GD::Graph module that can be treated as an "area" graph, but renders splined (smoothed) line graphs. See GD::Graph for more details of how to produce graphs with GD....

boxplot is a *perl5* module that uses GD::Graph, GD, and Statistics::Descriptive to create and display PNG output for box and whisker graphs....

xylines is a *perl5* module that uses GD::Graph, GD, to create and display PNG output for XY graphs with lines....

Overview Only three methods need to be overridden to create your own GD image of the data. render_year( YEAR ) The years that form the axis of the graph are rendered by render_year( ). A scalar pointing to the data for the year to be rendered is pass...

xypoints is a *perl5* module that uses GD::Graph, GD, to create and display PNG output for XY graphs with points....

This is a wrapper around GD to place points and lines on a X/Y scatter plot....

GD::Graph::histogram extends the GD::Graph module to create histograms. The module allow creation of count or percentage histograms....

This package is used for creation a smooth area chart....

GD::Graph::sparklines is a Perl module for creating sparklines using the GD::Graph infrastructure -- if you want a sparkline of your data, you can just replace use GD::Graph::lines; with use GD::Graph::sparklines; and it will "just work", assuming yo...

When deployed in production, the current value ought to be dynamically calculated based on a query of the database tracking contributions or volunteers or whatever the goal represented by the graph represents. my $result = GD::Graph::Thermometer->new...
