Change date format and where are the charts?

Hi,

how do I change the date format from yyyy-mm-dd to dd-mm-yyyy? I cannot find this in the configuration.

Also, i used to use the old version of Comunity surveys, and it used to produced bar and pie charts on the front end once the surveys were completed. Is this feature no longer availabe?

Finally, is it posible to focus the map on a single country (UK in my case?).

Thanks in advance
