Zooming when resizing

Hi all,

is it possible to zoom the diagram during resizing? I mean not to create overview window but perform zooming by getting the window smaller\greater (not to stretch the canvas picture but rescale the whole diagram).

Hi Anna,

I guess you want to change zoom so that same part of the diagram stays visible? Try recording the diagram's div size from window.onresize handler, and then scaling ZoomFactor by how much div's width changed. E.g. if the diagram div's became double the size (newWidth / oldWidth == 2), also double the zoom factor.

Regards,
Slavcho
