Using version 0.2.28
On Visitors -> Frequency & Loyalty there is a graph titled 'Evolution over the period' ( http://[mysite]/index.php?module=CoreHome&action=index&period=day&date=yesterday&idSite=4 ). Here one can choose viewing several graphs like 'returning visits', 'total time spend by returning visits', etc. The graph changes when I select one of them, but the legend always defines the line to be 'nb_uniq_visitors', which is incorrect.
Thanks, this has already been reported (e.g., #364 & #437) Translations in Flash graphs aren't handled yet.
Please monitor ticket #251.
