[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().
