I love this tool because it's so easy to set up dashboards using existing fields from your database or SQL Server tables in seconds! It has saved me countless hours of manual labouring over creating dash boards that are visually appealing but also functional/usable - which was my problem previously when relying solely upon Excel pivot charts etc (which were good looking at times!)It can be difficult finding out how best use features such as'slice' if you're not familiar enough yet they have great support via their forums available here:- https://www.viziblogs.com/.
If you've used other tools like Tableau then these will look similar although perhaps need more tweaking initially? However once getting into them all become very intuitively obvious quickly especially after playing around first before committing fully :).
