Re: change calculating with the selected data

for other, that has problem with measure

MPop = sum(Population[Population])

MTotalPop = CALCULATE(SUMX('Population';'Population'[Population]);ALLSELECTED('Population'))

MPopCumul1 = CALCULATE('Population'[MPop];FILTER(ALLselected('Population');'Population'[MPop]>=MAXx('Population';'Population'[MPop])))

and Measure Share
MShare = DIVIDE('Population'[MPop];'Population'[MTotalPop]) 

MShareCumul1 = CALCULATE('Population'[MPopCumul1]/'Population'[MTotalPop])

good luck
