only one category by date in a pie chart

[rafaelarbl]

one action has several situations differing on date like in the image below

i need to make a pie chart that shows only the latest situation for each action

i managed to make a measure showing me this, but i cannot put the measure on the legend of the pie chart.

any suggestions?

here's the measure i made

maxx(topn(1,'public fato_acao',CALCULATE(max('public fato_acao'[dt_status_acao])),desc),'public fato_acao'[id_situacao_acao])

@rafaelarbl , Not very clear, but dt_status_acao as legend and the measure above in pie visual
