change map data point colours

Hi jagdeep

As tested and searched, it is impossible to change map data point colors with the slicer. 

Besides, i'm afraid it doesn't support that when filtering to Location A, the map zooms to sales around Location A, but keeps showing all the sales from all the other locations on the map.

Here is a workaound, could you try to see if it satisfies your scenario?

add the "Location" column to a pie chart or other chart, then edit the interaction between the chart and map visual as "highlight",

then select the "Location A" from the chart, the "Location A" point on the map visual would highlight and other locations would become grey.

More details please see the reference:
