Ranking and displaying cities of shortest distance

Hi,

I have a data set that contains columns Country, State, City, Location X, Location Y; (X,Y) is the location on the coordinate. So anybody can help me on how to caculate the shortest distance starting from every city to any other instate cities and display those cities(with the first and second shortest distance) in columns?

 

Here's the original data:

and here's what I would like to show:

Pre-Appreciated!

Hi @Anonymous,

 

Try these two measures, please.

shortestInStateCity =
MINX (
    TOPN (
        1,
        FILTER (
            ADDCOLUMNS (
                CROSSJOIN (
                    ALL ( 'Table1' ),
                    SELECTCOLUMNS (
                        'Table1',
                        "City2", [City],
                        "Country2", [Country],
                        "State2", [State],
                        "X2", [X],

                    )
                ),
                "Distance", SQRT ( POWER ( [X] - [X2], 2 ) + POWER ( [Y] - [Y2], 2 ) )
            ),
            [Distance] <> 0
                && [State] = [State2]
        ),
        [Distance], ASC

Hi @Anonymous,

 

What's the distance? How can we calculate it?

every city is described as a point(x,y) on the coordinate, and the distance between 2 cities is calculated as D = sqrt((x1-x2)*(x1-x2) +(y1-y2)*(y1-y2)).

 

Thanks!

It works pretty well, thank you so much!

 

one question about the function Minx(): it is said on the MS DAX doc: 

Return value

A decimal number.

 

https://docs.microsoft.com/en-us/dax/minx-function-dax

 

but it returns the 'City' in my case. 

 

Thanks!

sorry, I can't.  The data I posted are similar to my real data.

 

every city is described as a point(x,y) on the coordinate, and the distance between 2 cities is calculated as D = sqrt((x1-x2)*(x1-x2) +(y1-y2)*(y1-y2)).
