Quick Start Tutorials - Script Interface (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 powerful and allows for the construction of graphs from virtually any database system running on virtually any platform.

Method Outline - the graph applet is incorporated into a a static HTML page but rather than supplying the data with PARAM tags or flat file, the graph is set to acquire data from a server side script. The server side script accesses the database and returns the graph data to the applet.

At page view time the script reads data from the database and will format the data for input into the either the graphing Applet or Servlet - hence producing a Real-Time Dynamic Graph with data direct from a database within the web page.

Note: This method may be applied to both Applet and Servlet forms of the graphing software.

To implement this method simply perform the following 3 steps,

  1. Construct the Data Script
  2. Construct the HTML Page
  3. Upload the Script, HTML page and jar file to your web server

Step 1 - Construct the Data 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:-

  • PHP
  • ASP
  • JSP
  • Java Servlet

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/PieData.php

ASP template script - ./TemplateScripts/ASP/PieData.asp

JSP template script - ./TemplateScripts/JSP/PieData.jsp

Java Servlet - ./TemplateScripts/Servlet/

When modifying the applet configuration parameters within these scripts please also refer to the following section in the Documentation,

Documentation -Pie Chart Configuration Options

Step 2 - Construct the HTML Page

In your web page place the following code, where you wish the graph to appear,

Adjusting the "width" and "height" element of this applet tag to specify the size (in pixels) of the desired graph display.

Using this option the applet will read all the configuration information from the standard applet <PARAM> tags. Simply add the <PARAM> tags, contained in the paramtags.txt file (click here), to your html between the <APPLET> and </APPLET> tag, adjusting the values to specify the characteristics of the pie chart.

For a full description of each property please see the following section in the Documentation,
"Configuration Options and Parameters".

Step 3- Upload the Script, HTML Page and jar file to your web server.
The final step is to upload the HTML Page and Data Script to your web server and place the
Piechart.jar file in the same directory as your web page.
