' The purpose of this PHP example is to demonstrate extracting
' data from an ODBC data source and populating a NetCharts
' chart with this data. The basic order of events is as follows:
' - Connect to the database and pass in the SQL statement
' - Open the database and extract the data
' - Populate variables with the data from the database
' - Close the connection to the database
' - Instantiate the applet and pass the variables in through
' the NFParamScript parameter.

<!--
Note: The "code=" attribute of the applet is pointing to the
netcharts4.apps.* package. This is done to avoid any classpath
conflicts that may occur on the system running NetCharts. If,
for instance, an older version of NetCharts is installed on the
system, and the CLASSPATH environment variable is pointing to
that package, then a conflict could occur that might keep this
example from running. By pointing specifically to the
netcharts4.apps.* package, no conflict will occur. Note that a
change will need to be made to the "code=" attribute in all of
the applet tags with every major new version upgrade of NetCharts.
(NetCharts 5.0, 6.0, etc.)
If this potential classpath conflict is not a concern, then set
"code=netcharts.apps.*". This will allow the applets to run
across multiple versions of NetCharts, without any changes.
