PrestaShop version 1.3 UserGuide – OCTOBER 2010
Compared with the first option, this second option includes comments on the various "graph
engines" used. You can also automatically select the way the statistics will be erased from your shop.
Erasing data will usually make the site more responsive, and thus improve the comfort of your
visitors. You have three choices, Never, Week, Month or Year, depending on your traffic and your
server’s performance.
