Visualisations blank until something selected in a slicer

I added the SlicerCheck to a test card to confirm it was picking up the slicer correctly and it shows a Y when sliced and N when not sliced. (which is great!).  When I add the SlicerCheck to my other card (the one I actually need it to work on), I am adding it to the visual level filters area, it doesn't give me options to filter by. I can click the arrow to expand but I can't type in the contains box underneath.  

this works on isolated card

SlicerCheck = if(calculate(distinctcount('DataSet'[Analyst]),allselected('DataSet'[Analyst]))=1,"Y","N")

My slicer is just a list of analyst names 'Dataset'[Analyst]

Please help me find out why the filtering isn't allowing me to click on anything.  *if the funcationality isn't there for filter a card's visual then it shouldn't have the option to add there. 

Can a KPI be used for this same purpose? Do it allow for the visual filter to be entered?

What would the work around be for a Measure, not a column? 

thank you - that works.

v-qiuyu-msft - great solution, thanks! +1

I did note that if you bring the measure onto a table as a column, then the calculation slows down considerably, so best to have it only on the visual level filter.

I noted also that you can't have it on the Page level or Report level filter, but you can of course drag it onto the visual level filter for other tables.

I'm not quite sure how this solves the problem. I thought I had a similar problem to OP. I need to have a table that is blank until someone selects something in the slicer (one or more values). This solution works fine for a slicer when multiple values cannot be selected. But when multiple values are selected, it does not work.

The formula is checking if there is one value selected. If we select one value this is fine, but multiple selected values are treated the same way as no value selected, this is where the problem is.

Excellent...that really helped...BUT where I have only one value in the SLICER Table it always reutrn the slicercheck to Y. Is there a way to get the same functionality with just one value in the slicer.

e,g, I have only one value. "SHOW' in the slicer and when the user select/clicks show on slicer only then it should display the data on visual and when the user deselect the SHOW on slicer it should reset the data. like I am trying to get the toggle button functionality from this.  Thanks

I created a measure to do this. The measure counts the specific number of dates selected. I figure I can use this to filter based on the number of dates selected, so basically "plot data only when 10 or fewer days are selected".

Date Filtered = calculate(DISTINCTCOUNT('Data'[Date]),ALLSELECTED('Data'[Date]))

I have a card on the report that shows the measure and it works appropriately. When I have nothing selected it counts all the unique dates (days). When I select one, two or whatever it counts correctly.

But when I add this to the filter on a visual it doesn't work. It's calculating the measure for each group of data (which is grouped by day and hour using the bin feature), meaning it always returns 1. How do I make this calculate for the whole page instead of per row/group in the chart?

Like joshcomputer1  and other that have comented, 
this tecniques works for some vizuals but not for others, i'm able to put the measure in the filter pane section for the other vizuals but i cannot click or edit it, it seems block and i don't understand why...

Did anyone got why?

how can I hide " No data available to display" when doing this measure filter please

Hi All,
The measure seems not working for me, Because I have select all option in my filter. If i select a value in the filter, report get filtered based on that, When select all option is selected, I didn't get any data. Please provide any possible solution to fix this issue
Thanks,
