Same process as before - when you first create each kind of chart it’ll take a while to fetch your data, subsequent charts will be created a whole lot faster. Eventually I’ll make a script to purge the data stored for anybody who hasn’t used the program in a couple of months so keep popping back if you get fed up with the waits.

As always comments are welcome. Oh and suggestions for a better name too..

I’ve made it automatically updating, so you only need to add your data once the very first time you visit, and after that it’ll check whether there should be new charts available. Maybe it should only happen a few days into the week - LastFM never get the charts out on time after all..

That and I added a few extra quick links, to 3/6/12/24 months previous. No more ‘wait a month for charts to refresh’ ;-). I should totally see if I can make this into a greasemonkey script..

PHP’s strtotime function is no end of brilliance - strtotime("-6 months") and strtotime("last sunday") are genius conceptions.
