pChart is a PHP class oriented framework designed to create aliased charts. Most of todays chart libraries have a cost, the project is intended to be free. Data can be retrieved from SQL queries, CSV files, or manually provided. This project is still under development and new features or fix are made every weekFocus has been put on rendering quality introducing an aliasing algorithm to draw eye candy graphics. Rendering speed has been dramatically enhanced since the first version, we'll still continue optimising the code! Saving web server speed and CPU is something that matter to us. We've created the pCache class to help you dealing with the fact that a chart can be computed once and displayed many times by different users. The pCache class can be used to simplify server side cache management. In green, the normal process : retrieve data, compute and display, in orange the cost saving path, retrieve the data, check if we have already computed it and display it!
