I downloaded the free non-joomla script for try-out and was fascinated how easy it was to generate any kind of reports or statistics from a given database connection. So I purchased for a little of 5$ the Reortico Joomla extension including the associated Joomla module. Installation was smooth as silk. With this extension I was able to embed statistics in table form and graphs of another third part Joomla directory extension, what I used as a base for a survey database and display it in a nice formatted way. You will need a bit time to find out all its possibilities and Peter, the developer, was giving such great support. Believe me after searching and trying so many different database report tools, I must admit it is the best available for Joomla.
