Calculating minimum distance between XY coordinates

I'm trying to determine the closest point to any given point on an XY scatterplot. For simplicity, data is plotted on a 10x10 XY axis. How can I calculate the minimum distance from each point to any ...

    Probably something like:

     

    Distance =
      VAR x1 = SELECTEDVALUE(Locations[X])
      VAR y1 = SELECTEDVALUE(Locations[Y])
      VAR __Table = 
        ADDCOLUMNS(
          FILTER(ALL(Locations),[X] <> x1 && [Y] <> y1)
          "distance",SQRT(POWER(([X] - x1),2) + POWER(([Y] - y1),2))
    RETURN
      MINX(__Table,[distance])

    Well, that's what I was trying to do with that filter. You would need some kind of ID or Index. So if you had that identifier, just grab the identifier with a SELECTEDVALUE and then filter on that identifier <> that.
