PHPlot is a PHP class for on the fly graphs generation. It was started by Afan Ottenheimer in 1998 as an opensource project, and is now co-developed with Miguel de Benito thanks to sourceforge. It is distributed under the terms of the GNU General Public License, and the PHP license. You can always obtain the latest source from the sourceforge project page, please do also check CVS, we try to have it always working there.

• 3D shading for pie and bar graphs.
• Different line types: solid and wholly customizable dashed ones.
• Can draw error margins along y-axis when supplied in data.
• Highly customizable canvas: titles, labels and ticks can be placed anywhere, with any color and everything gets automagically placed without overlapping.
• Vertical and horizontal grids.
• Legend. Different types on the works.
• TrueType font support.
• Linear and logaritmic scales.
• Several output formats: jpeg, png, gif, wbmp (those supported by your GD)

• Horizontal bars.
• Simple isometric 3D plots.
• Automatic placement of several plots in one image.
• Better or automatic management of many drawing options (ticks, labels, etc.)
• Subclassing for optimisation: move features into subclasses for optional use and leave a fast core.
