It won't work in a calculated column. Columns are only calculated during data refresh and so do not take into account any slicers or filters. Why do you need it in a column rather than in a measure? Is it something you could achieve with a fields parameter ?
I use parameter to display the data on a map when selected in a slicer. Beside this i need to add a legend on the map that divides the displayed data into 4 categories. Any way, I need a solution to switch columns based on the selected value of the slicer.
I think a fields parameter might work, add both measures to the field parameter and then use the slicer that automatically gets generated. add the fields parameter to all visuals and it should work I think.
That works and I have tested it. My case is a bit different. I need one parameter value to do to things. First it populate the select column/measure on the map and secondly it process and categorize the select column into a categorical feature and then add on the map as a legend value. The first works but the second does not work.
The only thing I can think of is to add another column to the fields parameter table, link it to whichever table is driving the categories, so that a selection of the fields parameter filters the categories.
