how to remove 0 bar from stacked bar

we have our own stacked bar visualization, where we need to eliminate bars with 0 values. I tried removing this property from the js minPointLength: 0, ![alt text][1] However, this just eliminate the bar and not the visibility of 0 from bar and shows overlapping values on same bar(see pic).But i want to remove the 0 at all from graph Any leads would be helpful.
