Trouble with the graph editor

I have Blender 2.62 and the foundation book for it. I’ve done the first animation with suzanne exactly like the one in the book. But my graph doesn’t look like it should. I think the graph is reading the z rotation with large numbers such as 90. How do i make my graph look like the one in the book?

I don’t have the book yet or I could help you out…

I’m pretty sure they guy who put this book together is here…
