Highcharts sparse data - hide empty values

I have data that can be very sparse - that is many values are zero.

In this case I'm not so much interested in the zeroes but more the values that actually have a value so I was wondering if there wa开发者_开发百科s a way to not display columns which are empty.

Example fiddle: http://jsfiddle.net/HUBhj/

Think a case like this which is even more sparse with even more columns per category.

I have tried to read the docs as good as I can but I may have missed something.

As far as I understand it, it is not possible to simply omit empty values. Your best bet in this case is to pre-process the results as described in the documentation.
