negative value on line chart

Hi!

I am trying hard to remove the -ve value on the Y - axis for the line chart but unable to do so, can anyone please help

As refered on other articles, I have tired if(measure>0, measure, blank()).

Further, we have updated the Y - Axis with 0, but then also not able to do so

Currently I have both of these are applied on my measure if(measure>0, measure, blank()) and the 0 start value

But still we are facing the same result
