I would think that you would need to construct the input file for ggobi 
from your query output.  There are many ways to do this, I would 
suppose, but if I were to do it, I would make a perl script that 
accepts some parameters, does the SQL query, and outputs the results 
with appropriate formatting to a file.  Then call ggobi with that file 
as input.  Pretty simple, but you still have to do the work of 
determining the file format for ggobi and generating that file format 
on your own.

As an alternative, you could use a system like R 
(http://www.r-project.org) that has plugins that allow postgres access 
and access to ggobi.

Hi All,

How easy or difficult is it to get ggobi/xgvis working with postgresql?!
Is it possible to write a query and send the output straight to
ggobi/xgvis without much work?
Any pointers.

Thanks for your help.
