Easy Chart DB Trend Y Axis Range

Running Ignition 8.1.16.

I'm using an easy chart to display some DB pens. The query returns results just fine, but when I change the Y axis range when in manual (not auto range) mode it re-runs the query. Is this expected behavior? I would not expect the query to re-run just because the y-axis display area has changed.

Yes. Because you are re-configuring the component.

To avoid it, you would have to supply a custom axis range object that exposes its limits outside the component. Then you could re-range without requerying.
