	Hi, I need overview control with a small change. Right now overview is displaying the diagram in a reduced size. But I need overview in such a way that, if there is only one node, that node has to occupy the entire overview control. In short the overview has to show the diagram occupying the entire overview. I don't need the navigation feature in overview. Can I achieve this? Thanks Kiran B

	Hi, The overview control fits the entire rectangle returned by Diagram.getBounds(). So at this time you can achieve that only by setting a smaller diagram.Bounds that exactly fits the diagram's content. I hope that helps, Stoyan

	Hi Stoyan, Could you please let me know which is the method in Overview is calling Diagram.getBounds(), so that i can override and achieve the functionality i needed. Also if there any way to get the Diagram bounds which is covering the shapes alone? ie the co-ordinates of the smallest rectangle which covers all the shapes in the diagram. Thanks Kiran B

	I can't see any easy way to override this right now; we'll try to add some options for how the diagram content fits within the Overview for next release. If you have the source code you could check the init() function in Overview.js and replace it with a custom method, but it uses the width and height of the diagram canvas element already calculated from Bounds, MeasureUnit and current zoom level of the diagram object.
