This class is meant to generate bar graphs defined either programatically calling the class functions or using definition file to specify the graph characteristics.
The graph definitions file structure is very simple and so it is probably a better way to create graphics on the fly.
It supports axis background or border color, title text and color, graph background color, bars background and border colors, padding distances, etc.. Transparent background and transparency levels for the entire image are also supported.
The bar graph images are generated in true color in PNG format.
Draw pie charts, bar, line graphs from definitions
This package consists of one base class that provides common functionality to draw graphs and charts with a title, an axis, a scale and a legend. There are also other derived classes specialized in drawing pie charts, line or bar graphs.
The details of the different types of graphs are configured in separate configuration files to simplify the creation of new charts.
The graphs are outputted as true color images in the PNG format.
