Removing null data/slice from pie graph
===

I have a highchart that when there is no data for the series data element, pie chart will label the segment as "Slice". I have found if I change the null to an empty string that the segment label and connector will be removed as desired. There could be several null elements for whatever reason, but without a valid attribute for the segment label/legend I don't want it displayed.

I have found that when the very first data element in the series has the empty string for this.point.name, then I get something funky (undesirable).

You can have the empty string for this.point.name anywhere but the very first element and the graph is output as desired. Any suggestions?
