The following brief description is intended
purely those who are interested. It is not essential
to understand this page in order to use the
graphing software.
The graphing package is a piece of software written entirely within the PHP language. The software can operate on any
web server with a PHP Engine. The set-up and install process is very easy and simply requires copying a few files to your
web server.
( see Quick Set-UP and Install for details )
A graph is added to a web page using the standard
html <IMG> tag (the same tag which is
used to add images to a web page). In this case
the <IMG> tag is set to point at the graphing
software, rather than an actual image file.
When a user's browser views a page which contains
the graphing <IMG> tag the following will
occur (automatically).
All of this happens automatically and very
quickly, in fact the user will not notice the
difference between this and any other image
within the page.
Unlike some graphing software packages, at no point is the graph image stored as a file on the web server. The graph
image is always created 'on the fly' and all system resources are immediately released. This makes the graphing package
incredibly scalable and easy to manage.
