If I understood correctly, you could use something like
LOAD * INLINE [
Colonne A, Colonne B
LOAD [Colonne A] as Numbers, count([Colonne A]) as ACount resident INPUT group by [Colonne A];
outer join LOAD [Colonne B] as Numbers, count([Colonne B]) as BCount resident INPUT group by [Colonne B];
NOCONCATENATE LOAD Numbers,
if(IsNull(ACount),0,ACount) as ACount,
if(IsNull(BCount),0,BCount) as BCount
drop table TMPRESULT;
Then just create a straight chart with dimension Numbers and values ACount and BCount and calculate the Delta from BCount-ACount. Use Visual Cues to color the difference as you like.
