Reports and getting data to show up

Trying to make a report that shows a history tag's value charted for the last 24 hours, and am struggling unnecessarily. Any resources other than the inductive automation videos that could be actually useful? Those videos show literally nothing applicable to what I'm doing haha.

I've created a tag history data source:

but attempting to access the individual tags from the key browser doesn't work, as in there is no drop down menu for the data source:

Am I missing an obvious and crucial step here?

Can you prove there is historical data being stored for these tags?

As in other than this?

That's just showing the live values of the tags - although the clock icon does indicate that history has been turned on.

Create a view (Perspective) or window (Vision), add a table and create a binding to the tag history over a date range where you expect to have some data. See what gets displayed.

Yeah it seems like there isn't historical data being stored.

Show us the tag datatype and the history configuration.

And it is an OPC tag

Are there any faults in the Gateway regarding DB access?
Also have the values of those tags changed since you added them to the historian?

No database faults and yes the values have changed, I noted them all down to be sure of it even.

Never mind, oh my lord it was the simplest thing ever, forgot that Order of the parameters matters, start date needed to be after end date, working now
