What is nb_uniq_visitors?

On the “Last Visits Graph”, it shows nb_uniq_visitors instead of… what should it be??

Even in the graphic on the Home page http://piwik.org/ you will see it.


Looks like a little bug in the code. Can it be fixed?


this is already in TRAC: http://dev.piwik.org/trac/ticket/437
it requires some significant work to get the labelling right, but this is on our Todo list as currently the graph won’t display the right legend.
