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], "Y2", [Y] ) ), "Distance", SQRT ( POWER ( [X] - [X2], 2 ) + POWER ( [Y] - [Y2], 2 ) ) ), [Distance] <> 0 && [State] = [State2] ), [Distance], ASC ), [City] )
2ndShortestInStateCity = MINX ( TOPN ( 1, TOPN ( 2, FILTER ( ADDCOLUMNS ( CROSSJOIN ( ALL ( 'Table1' ), SELECTCOLUMNS ( 'Table1', "City2", [City], "Country2", [Country], "State2", [State], "X2", [X], "Y2", [Y] ) ), "Distance", SQRT ( POWER ( [X] - [X2], 2 ) + POWER ( [Y] - [Y2], 2 ) ) ), [Distance] <> 0 && [State] = [State2] ), [Distance], ASC ), [Distance], DESC ), [city] )
Best Regards,
Hi @Anonymous,
What's the distance? How can we calculate it?
Best Regards,
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!

Best Regards,
It works pretty well, thank you so much!
one question about the function Minx(): it is said on the MS DAX doc:
A decimal number.
https://docs.microsoft.com/en-us/dax/minx-function-dax
but it returns the 'City' in my case.
Thanks!
Hello @Anonymous
could you show your real dataset?
thx
Did I answer your question correctly? Mark my answer as a solution!

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)).
