Is it possible to analyse all websites (which I have added to Piwik) statistics (general statistics) in the same page?
For example: If the daily traffic for example1.com is 100 and the daily traffic for example2.com is 200 then it need show 300 for all websites statistics (general statistics).
Briefly I need to add “All Websites” section to the place which I tagged on this image: http://postimage.org/image/j7or1gis/
