The Servlet is setup here to read both the configuration data and the graph
data from a server side processes, in this case a Java Servlets running on our web server.
and here is the HTML code,
<img src="http://localhost:8080/servlet/AreaGraphServlet?
config=http://www.jpowered.com/area_graph/Examples/areaprops.php&
data=http://www.jpowered.com/area_graph/Examples/areadata.php"
width="460" height="440">
The areadata.php ( click
here to view code ) is a simple PHP script designed to demonstrate how a server script can be used to return data to either
the graphing applet or servlet. In practice this routine would be expanded to first gather data from any number of data sources.
eg. databases, files other server processes.
The areaprops.php ( click
here to view code ) again is just a simple PHP script to demonstrate the method. Again, in practice this method would be expanded
to derive data from a number of data sources.
For a full explanation of and range of values for the above parameters please
see the Documentation - Configuration Options».
