Zoom to fit not working

Hello,

On a DiagramView the method zoomToFit() doesn't seem to do anything. My chart is zoomed in still. I'd ideally like it so that it's an overview of the whole thing.

DiagramView diagView = (DiagramView) findViewById(R.id.diagview);

diagView.setBehavior(Behavior.Pan);
diagView.setAntiAlias(SmoothingMode.AntiAlias);
diagView.zoomToFit();

Hi,

Have you populated your diagram before calling zoomToFit? It sets ZoomFactor just once to fit current diagram contents, and won't continue zooming out automatically as you add new nodes.

That makes sense, I've moved it after I create and populate my diagram.

...
layout.arrange(diagram);

and then call zoomToFit()

diagView.zoomToFit();

But that did not do anything either.

Are you sure there aren't any calls to zoom methods done later? E.g. replace the zoomToFit above with setZoomFactor(10) to see if the DiagramView will draw at 10% scale.

Yes, that works OK, it zooms out a lot.

layout.arrange(diagram);
diagView.setZoom(10);

zoomToFit result depends on current size of DiagramView. What are you seeing in log window if you print out view's getWidth() and getHeight() values?
