	It's determined by Diagram.Bounds. Regards, Slavcho Mindfusion

Regards, Slavcho Mindfusion Thanks for your reply!! but now I have a need,The Mindfusion default drawing origin (0,0) is in the upper left corner, I want to set the origin of the drawing origin (0,0) to the bottom right corner, do you know how to implement it ? The width and Height of Diagram.Bounds can not be set to a negative number, So I need to know how to set the scale of the ruler to be negative number!

	You can set Diagram.Bounds to new Rect(-width, -height, width, height), which should end with 0,0 at bottom right. If you need the coordinates to grow from right to left and from bottom to top, the diagram does not support that for its intrinsic coordinates, but you could set Ruler's NegatedX and NegatedY properties to show them as such to users.
