How to Change the Direction of a PowerPoint 2007 Diagram
If your PowerPoint diagram is horizontally oriented, you can flip it over so that the rightmost shape in your diagram becomes the leftmost shape, and vice versa. If there are arrows in your diagram, PowerPoint changes the arrows to point the opposite direction after you flip it. You can’t flip vertically oriented diagrams this way.
Follow these steps to flip a horizontally oriented diagram:
1Select the diagram.
Clicking anywhere on the diagram should select it.
2Select the (SmartArt Tools) Design tab.
The Design tab pops up.
