Hello

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.

Example:

URL Shortener with Statistics and Chart.

Creating your own Url shortener
Statistics on your URL Shortener

Best Regards,
Matheus
