If you ask piwik for visitors evolution, daily, weekly and montly screen show unique visitors, while yearly doesn't.
That happens in the resume with graph widget.
Please check your web server log file. If it says php was unable to allocate memory, then you'll have to increase your max memory_limit (php.ini).
Otherwise, post the error message here, so we can investigate further.
Seems to be that this is wanted.
76 if($view->period != 'year')
78 $view->urlSparklineNbUniqVisitors = $this->getUrlSparkline( 'getEvolutionGraph', array('columns' => array('nb_uniq_visitors')));
79 $view->nbUniqVisitors = $dataRow->getColumn('nb_uniq_visitors');
I guess, it would make sense to display it for day only, 'cause the value is inaccurate for other periods.

Evolution graph should now be shown in every period.
Should we add a note to the text (if period is not day) explaining that this value is a sum of all daily values?
I think it looks good like this :)
