PowerChart.config.startDate property errors

8.1.2-RC1

The error below seems misleading in the designer. The closest property I find related to the error is rangeStartDate and rangeEndDate which are both null.

EDIT: This PowerChart is from the Exchange (Ad-Hoc Trends: Ignition Exchange | Inductive Automation). When I drag a new Power Chart on my view I don’t see the errors.

Those component propertiess are hidden because you’re in “realtime” mode (config.realtime as a component prop). They are used to create the start/end points for the query that is made when the chart is in “historical” mode. Those properties are updated automatically as you interact with the chart, but if you’re setting them manually, just make sure to provide a valid Date object.

Thanks @jball. I was able to correct the error by switching to historical mode and setting a date.
