How to hide empty values from a column chart

Hi all

I have 3 columns in a chart and one of them has a value of zero for a given year. I´d like to know if it´s possible to get rid of this column since it´s taking unnecesary space:

I tried using null instead of zero and the chart would just show an empty space, which is precisely what I´d like to have removed.

Is this possible?

I tried this measure: 

Unit_Cases_BP = 

var _bp =

SUM(Query1[[Unit_Cases_BP]]])

Return 

IF(_bp=0,BLANK(),_bp)

 Thanks.
