CGI Export Tool

This Tool allows basic access to Channel Archiver Data  over the web:

• List Channel names, maybe filtered by a regular expression
• Get start/end times for the available data
• Retrieval of data in spreadsheet format
• Simple 2D & 3D plotting.
  This interesting feature is implemented in a highly portable way by calling GNUPlot. Hence it is available for Win32, Linux and Solaris, maybe more systems.
  Though response times for the examples given below are well within 5 seconds for 2D, 10 seconds for 3D, this is not meant to be a replacement for an optimized Win32 or Unix tool.

• Setup information...

Note that the ArchiveEngine has a built-in web server. That one allows you to monitor the ArchiveEngine status and configuration, not archived data! This different issue is described in the ArchiveEngine section of the manual.

Usage

The compilation and installation is described in the setup section. The creation of web pages is described in the HTML specs on http://www.w3.org as well as in thousands of books.
From then on, few users had problems with understanding how to enter the channel name into the name field and picking the start and end times from the start and end time selector boxes (see the following screenshots).
If you follow the example setup, the test web pages should include links to the web pages mentioned below under "Usage Details". This is helpful in explaining the remaining, less obvious options for "fill" etc.

Some Examples
