Trend Line not live function

Hi there,

I have a simple widget oh-label-card into a page UI of OpenHab 3.2 with trend line item set.

The widget displays the numerical data and the trend line correctly but the trend line does not update, only one browser refresh updates the it’s curve.

Is there any way to fix this?

No, as I understand it the graph is only rendered when the widget is initially created. It would have to be constantly polling the persistence REST API endpoints to keep up to date which is not supported as I understand it.
