I have a need to convert a reports Tag Historian Query results to a dataset. Could anyone tell me how to achieve this?

Here’s a mockup of the report data source:

I want to use the data from the 1st data source in the Script without having to re-query the database.  
When I log the type of the the results from the Tag Historian Query I get type _com.inductiveautomation.reporting.common.api.QueryResults_

Thanks

`com.inductiveautomation.reporting.common.api.QueryResults#getCoreResults` returns a Dataset - just call `data["tag_history"].getCoreResults()`.

Thanks @paul-griffith.  
I just found the reference in the docs for that.
