I am testing the Advanced Trellis chart for our organization and while in general it looks like just what we need, it sometimes goes completely white depending on filters. There is no consistent explanation when it happens or doesn’t happen.
This feels like a bug … it happens both in Power BI Desktop but also when publishing to my own personal Power BI Web Reports.
Attached you can see two screenshots, one for 2016-2020 where everything works and then when I changed the filter to 2017-2020 it goes blank … so it cannot be the data.
removing 2016 and the charts are gone …
