Displaying a Data Label from a Measure in Percent Format in a line Chart

Hi, 

Actually I have a measure which is this: 

Operational Utilization = (SUMX('Hours Table', IF('Hours Table'[Utilization] IN {"SALES"},'Hours Table'[Posted Hours], BLANK()))) / SUM('Hours Table'[Posted Hours])

Which is basically calculating a percentage value. 

I could use the result to visualize it in a graph like this way:

However I would like to display those data labels as a percentage format "##.##%". 

I created another same measure but formatting it to percentage this way: 

Operational Utilization Formatted = FORMAT((SUMX('Hours Table', IF('Hours Table'[Utilization] IN {"SALES"},'Hours Table'[Posted Hours], BLANK()))) / SUM('Hours Table'[Posted Hours]),"00.00%")

If I enter that measure in a data card it displays the correct result in percent format. but If I try to enter that value in a values field in the line chart I can't. 

Don't know what it is... maybe the formatting way I'm using ended up converting the value to a string and the chart doesn't receive those formates in the values field. 

Please help.
