Sort by value

i hope this could help you visual.

old situation:

you have 4 separte measures

create a separte table for the legend. 

create a switch that combine your measure to the table. 

it would look like this.switch =

VAR Legend = SELECTEDVALUE(Table1[Column1])
RETURN 
SWITCH(TRUE();
    Legend = "Proposta2"; [Measure 2] ;
    Legend = "Proposta3"; [Measure 3];
    Legend = "Proposta4"; [Measure 4])

Now you have 1 measure that you can sort. 

choose you visual and i think you are done. 

change your setting in the colors if you want every measure to be a differnt colour.

Thanks for help, I've slightly changed a dax formula.

switch = SWITCH(Teste[Column1];"proposta1";[Media_Impacto1];"proposta2";[Media_Impacto2];"proposta3";[Media_Impacto3])

Teste = Table Name 

Media_Impacto = my measure from different tables (no relationships tables)
