Can one suppress labels in a stacked bar chart when 0?

I have created some horizontal stacked bar charts and when the first couple of segments are 0, the labels get messed up (appear in next segment, etc). Is there a way to suppress the label when 0? It would make sense to have this as the default since there is never a segment in which to show the 0 label since it has zero length.

You may set template for label that will set either an item property or an empty string. For example, if label represents sales property, it could be as follows:

label: function(obj){ return (obj.sales!=0?obj.sales:"") },

Perfect! Just what I needed.
