Overview GOJS highlight box is taking full box

That’s interesting. Initially the Diagram.scale is really small. A bit less than 1/2000. Which oddly enough is the inverse of about how tall the viewport is. So I bet the value of Overview.documentBounds is 1x1. Could you check that please? And the value of the observed Diagram.documentBounds – what is it?

If so, then the problem is that the Overview, even though you say it is observing a Diagram with an HTMLDivElement, is overviewing a diagram with nothing in it. I’m not sure why it zooms out so far, though.

Right now i have leave but will check it tomorrow and will update you…
