I have warning generating for a relative mode EasyChart every second, coinciding with its update rate.

There is no other information and I’m not sure how to diagnose where this is coming from in the console?

I found it… it was a mouseover text binding set to display the start and end dates of the chart when it’s in historical mode. In realtime mode the enddate is None and it was causing issues in the function i was calling. I would have expected this to throw an error instead of just a strange warning with no info though?

Was this in the client, or the designer? There are a few places where we only throw an error in the designer to avoid showing (potentially confusing) errors to operators.

Thanks Paul, this was in the designer that it was only showing this warning. There was no error box that showed up
