[Solved]-highcharts column charts show sum single 0 when entire column data total is 0-Highcharts

you can use loop on each point, and remove stacklabel's svg object.

if that is enough to pick the middle column, and show a zero above, then something like this would do the trick: http://jsfiddle.net/6hxpu/20/

of course if you have even number of columns, the zero won't be centered. that case i think the best you can do is to find where to put the zero, based on the column heights and draw it directly with highcharts.renderer().
