Plotalot was recommended to me as the ideal companion for Fabrik and I have to say I have not been disappointed at all.
Plotalot is easy to use and the results are just plain "beautiful" to look at. Plotalot 3 uses Google's visualisation API.
I would say that you need to be able to write mysql queries, and to be fair the author points that out clearly and gives good advice in the excellent documentation.
Overall I would thoroughly recommend this product to anyone looking for an easy to use and robust graphing extension.
Xcloner was the answer - It just works brilliantly! It's easy to install and it's just one click to backup and one click to recover.
First class software as it should be!
Highly recommended! :)
