I’m just not sure there’s an easy solution here. This is a common request I’ve seen a few times now.
This was a recent one I replied to
There is a solution contain within this one. It does make it possible to complete something like this but it’s quite complicated I have to say.
My personal recommendation (and how I always do it) is to not have the month slicer at all on the page. Make the user select within the month and year chart to select the month/s. Then have another chart that shows the results by day that get filtered with any selection. I personally feel this always looks great.
