Dynamic Page Construction (via PHP, ASP, JSP or Servlet)
This method provides the ability to add Real-Time Dynamic
Database Graphing to your web pages. This method is extremely
flexible and allows the construction of graphs from virtually
any database / database system running on virtually any
platform.
Method Outline
Here the graph applet is incorporated into a server side
dynamic page script (eg. PHP, ASP, JSP or Servlet). Within
the script the the data values of the Applets PARAM tags
are filled in by the Web Server at page view time.
At page view time the script reads data from the database
and constructs the Applet PARAM tags - hence producing a
Real-Time Dynamic Graph with data direct from a database
within the web page.
Note: This method may be only be applied to the
Applet form of the graphing software.
Implementation
To implements this method simply perform the following 2
steps,
- Construct
the Dynamic Script
-
Upload the Script and jar file to your web server
Step
1 - Construct the Dynamic Script
The dynamic script can be constructed in any language of
your choice. Most Web Servers these days come set up with
a dynamic scripting language which is configured to access
your database system. For convenience we recommend using
the language already configured on your web server.
(if
you haven't used or are unsure about what's already available
on your web server then you should in the first instance
speak to your Web Server Administrator or ISP Hosting
company ).
The following are the most common Scripting languages and
cover over 90% of web servers in use today,
In the TemplateScripts directory you will find template
scripts which are designed to provide a base from which
to tailor a script for your implementation. You are free
to copy, modify and utilize these scripts in any manor you
wish.
Simply pick, from the links below, the template script
for your environment, modify where indicated and upload
to your web server.
PHP
template script - ./TemplateScripts/PHP/BarAppletDB.php
ASP
template script - ./TemplateScripts/ASP/BarAppletDB.asp
JSP
template script - ./TemplateScripts/JSP/BarAppletDB.jsp
Java
Servlet - ./TemplateScripts/Servlet/BarAppletDB.java
When modifying the applet configuration parameters within
these scripts please also refer to the following section
in the Documentation,
Documentation
- Bar Graph Configuration Options

Step
2- Upload the Script and jar file to your web server.
The final step is to simply to upload the script to your
web server and place the SHbarchart.jar
file in the same directory as your script. At only 15kb
this jar file contains all the applet code for producing
the graph in your page and as such is very fast to load
and run.
