7 – how not to display a sum of value 0 with the aggergation module of views

I'm using the aggregation of views and the module, I'm doing groups and compressions from taxonomy fields and a sum-of-columns action, how can I hide sums with a null value? the conditional views of the module have no effect, I have also tried all the parameters of "behavior without result". Code or hooks are welcome, any help will be appreciated.
