I am making a simple bar chart that shows the count of a bool tag every 12 hours. The tag has been "False" for over 12 hours. To my surprise, my chart showed data this morning after resetting my trial. I queried my DB, but it shows correct. I have reset my trial since this, and have not been able to recreate.

Any ideas?

It's not quite clear from your question what you're trying to get or what you did get.

The manual on [Tag History Bindings in Perspective | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.1/ignition-modules/perspective/working-with-perspective-components/bindings-in-perspective/tag-history-bindings-in-perspective#aggregation-mode) states,

> Count - Returns the number of times a value was recorded

I'd expect that to return the number of times '0' appears in the column and the number of times '1' appears in the column, etc.

Disregard, I had an incorrect tag path causing unexpected behavior.
