Hi @tsynenkyy ,
As a workaround, you could create a seperate table with one column which has regions and countries as follows.
Then create a measure with SWITCH() function. For example,
MAX ( 'TableName'[Regions/Countrys] ),
Then put the measure into Values, put the Regions/Countrys column into X-axis.
