Image_Graph provides a set of classes that creates graphs/plots/charts based on (numerical) data.

Many different plot types are supported: Bar, line, area, step, impulse, scatter, radar, pie, map, candlestick, band, box & whisker and smoothed line, area and radar plots.

The graph is highly customizable, making it possible to get the exact look and feel that is required.

The output is controlled by Image_Canvas, which facilitates easy output to many different output formats, amongst others, GD (PNG, JPEG, GIF, WBMP), PDF (using PDFLib) and Scalable Vector Graphics (SVG).

Image_Graph is compatible with both PHP4 and PHP5 and can be used with both GD1 and GD2 (GD2 is recommended)

Image_Graph

This library provides a common interface to different image formats. This is achieved by using a strategy pattern in the form of a driver with a set of primitives. These primitives are selected to provide as much functionality for each format as possible, while still retaining a simple and common interface.
