I decided to implement a Chart vision of the access to a address of the last 30 days. THe system that I choosed is Open Flash Chart.
The new methods:
getAccess($id) - Return an Associative Array with the access by date and the total
formatData($data) - Receive the access of getAccess and transform it in a Numeric Array.
criarLabels() - Create the labels to the bottom part of the chart.
If you want to access it, you have to manually get the ID and use http://www.example.com/diretorio/chart.php?id=ID where ID is UID from the MySQL table.
PS: Don't forget the Rewrite Rules.
