Show a boolean tag history on sparkline

Is there anyway to get a sparkline to show boolean tag history like the easy chart does in this picture?

I’ve tried messing around with the system.tag.queryTagHistory() bound to the sparkline data, but can’t get it.

Hi i’m trying to do the same thing. I had hoped turning on “Prevent interpolation” on the Tag query on the sparkline data binding would help. But no luck.
