I saw in video from fibery channel it self about one report. And was clueless about which chart is used and how to create it ?
Hi!
If you use our Vacations template, then you have to create a report, choose three databases as a source - Vacation, Sick, Day on.
On X axis goes Count of Record field
On Y - Person field
To the grouping on the right - Entity database field.
Does that make sense? Or do you need any other details? 
Yes, That looks as expected. One question - how Entity database field visible in Vacation template and not in my space-databases ?
