I am using cardinality aggregation in TSVB.  
In metric graph, 'precision threshold' was used in 'json input'. like this...  
{  
"precision\_threshold":40000  
}

How to use it in TSVB?

Do you mean the metrics-visualization?

If so, that corresponding option (to inject custom json-params) does not exist in TSVB.

When using cardinality aggs in TSVB, I want to know how to use the 'precision\_threshold' option.  
Because the default value of precision\_threshold is used, the cardinality result value has a lot of errors.
