Vertical bar graphs not working (no replies)

I want charts similar as this:

http://demo.piwik.org/index.php?module=Widgetize&action=iframe&columns[]=nb_visits&widget=1&moduleToWidgetize=VisitsSummary&actionToWidgetize=getEvolutionGraph&idSite=7&period=day&date=yesterday&disableLink=1&widget=1

... as vertical bar. But is not working:

http://demo.piwik.org/index.php?module=Widgetize&action=iframe&columns[]=nb_visits&widget=1&moduleToWidgetize=VisitsSummary&actionToWidgetize=getEvolutionGraph&idSite=7&period=week&date=yesterday&disableLink=1&widget=1&viewDataTable=graphVerticalBar

Any way to make it work with proper legend etc like the evolution?
