Now back to the point of this post. As of June 2019, it is possible to pre-filter slicers as well. It may seem weird, but this previously wasn’t possible – it seemed weird to me, anyway. This is now fixed and it is possible to use the side filter pane in the same way as other visuals. I can think of quite a few useful scenarios, including:
– Hiding the dreaded (Blank) in a slicer. [Actually, please don’t do that, but instead fix your data model].
– Filtering out items not relevant (eg category managers may only want to see their own products)
– Hiding items with no sales
Read on for a few examples of how to use this.
