How to get count aggregate as 0 in vega-lite+Kibana?

Hi,

Query : Trying to get some aggregations through Kibana's vega-lite visualization, however when there are no records, the aggregate is not shown as 0.

Is there any way for aggregate to start from 0,1,2, something like this, instead of 1,2,3

Thanks.

@nyuriks - can u plz take a look when you get a chance ?

Thanks
Rashmi
