Statgraphics Web Services

STATGRAPHICS Web Services are designed to be called by user-written web applications to perform various statistical calculations and return tabular and graphical results. In a typical implementation, a web application creates an XML script which is sent to the web service together with the data to be analyzed. The web service processes the request and returns XML results, HTML tables, or graphics images for the web application to display.

STATGRAPHICS stratus software is an example of a web application that accesses the STATGRAPHICS Web Services.

XML Scripts

User-written web applications communicate with the web services using the STATGRAPHICS XML Scripting Language. Using the scripting language, system globals can be set, data files can be accessed, and statistical procedures can be invoked. Scripts developed with the XML scripting language may be executed by:

1. STATGRAPHICS Centurion Version XVI or later.

2. The STATGRAPHICS Online Web Services. 

A STATGRAPHICS XML script is a text file containing XML instructions similar to the following:

script(1)_(1)

The various sections of the script set global options and graphics parameters, describe the data source, and specify the statistical procedures to be performed.
