if has one filter do not rank

[giorgiokatr]

hi there

i have a dax function 

 RANKX(ALLSELECTED(Branches[SectorDescription]);[% Diff.];;ASC;Dense))

and this way i present in a barchart sectors with their ranking

i want when i select one sector from a drop down filter in diagram to not have ranking

i tried 

 IF(HASONEVALUE(Branches[SectorDescription]);0;RANKX(ALLSELECTED(Branches[SectorDescription]);[% Diff.];;ASC;Dense))

but everythin in diagram goes 0 even when i do not filter sectors from drop down filter
