	Hello, what my problem is, when I with a finger try to move the diagram on the screen of mobilephone, but I find that, the diagram can only be moved to top and left, can not be moved to right and down. I show this problem by the picture I upload. My code is fast the same as the example Code in "DroidDiagram Programmer's Guide", only add diagView.setBehavior(Behavior.Pan); Besides, the example Program in "DroidDiagram Programmer's Guide" also has the same Problem.Could you tell me how can I move the diagram freely on DroidDiagram-Background-area? In other word, it should be enabled to move to right,left,down and top -area. Thank you very much indeed!

	Hi, The scroll range depends on Diagram.Bounds value. If the diagram content is at the top-left of Diagram.Bounds, you won't be able to scroll it to bottom-right because scroll position would end up outside the Bounds rectangle. You could set diagram.Bounds to a rectangle created by inflating Diagram.getContentRect() by the screen's width and height to enable scrolling the content to all edges of the screen: Code // build and arrange the diagram // ... RectF bounds = diagram.getContentRect(false, false); bounds.inset(-screenW, -screenH); diagram.setBounds(bounds); where screenW and screenH and the screen dimensions specified in diagram's MeasureUnit. I hope that helps, Stoyan

	I can not find a method called getContentRect() in Android-Mindfusion, in other word, diagram.getContentRect(false,false) can not be used in Android development. could you give me a another alternative Method that exists in Android-Mindfusion? thank you very much.

	Sorry, I haven't noticed it's internal. The same method is called by resizeToFitItems, so you could change the code to this: Code diagram.resizeToFitItems(0); RectF bounds = diagram.getBounds(); bounds.inset(-screenW, -screenH); diagram.setBounds(bounds);
