This example demonstrates how to implement the applet so that the graph data
is acquired from a database. Here we set up the applet to acquire the configuration data from a text file and the graph data from
a server side process which in turn acquires the data from a database.
The Graphing Software provides several methods by which data can be acquired
from databases. For a full discussion on the various methods and Template Scripts please see the
The configuration data is acquired from the text file barprops.txt

The SVbarDataScriptDB.php is designed to
retrieve product sales data from a MySQL database, from a table with the following structure,
|Table Name : SalesBar
Our PHP script will pick out the sales figures for three products ( ProductX,
ProductY and ProductZ) and return the data in the correct format for the graph.
The method is as follows,
- Set the output characteristics for the return data
- Establish the database connection
- Build the query statement and retrieve the database records
- Process the database records and return the Data
- All finished so close the database connection
The full script code is contained in the SVbarDataScriptDB.php
(Click here to view the code).
For a full explanation of and range of values for the above parameters please
