I’m getting a Component Error only when using a DB Table Historian query on the Power Chart. If the date range entered returns no data and you have “pointCount” set to -1 or 0 (which is required to prevent interpolation of the data), then the component doesn’t fail gracefully. To get the component back, I have to select a valid time frame where data exists, then re-add the pen (or simply add another pen to cause the component to re-render).

Or, it may be related to selecting such a narrow start and end date that it forces the read-only range selector’s “rangeStartDate” and “rangeEndDate” to be the same value and causes the Component Error. I don’t know enough about the underlying design of the component to know which is causing the issue.

I am on version 8.1.45

If you can reproduce in a real browser session, can you get the full error message from the browser console and send it in to support?
