This package can generate Bar, Pie, Line graph images.

It can generate chart graphs from arrays with the date for the charts.

It generates an image as a local file so it can be used for serving the chart as image directly.

The chart image width and height, the labels text and rotation angle, the pie radius and angle, etc., are configurable parameters.

Details


cwGraph class to use the methods of pChart to create fast charts
with basic knowledge of pChart library.

pChart library is required for usage.

This provides a layer of abstraction for other libraries but only 
pChart was implemented.

In the example directory can be found a basic example that I got
from old code using this class.

Example in:
src/php/example/example.php
