Flex will determine the most appropriate angle given the number, size, and spacing of the labels and the size available to the chart. But you can set an explicit value if you know you want a specific rotation, regardless of size etc. If Jeff's suggestion got your angles rendering, then you can explicitly set the labelRotation (I think that's what it's called, but it's something with the word rotation in it...you can find it in the docs) property on the axisRenderer to whatever degree value you want.
Thanks - Susan Chang made that suggestion and that's what I'm using. I'm wondering - in your tutorial, which was where I started, were the labels supposed to rotate without explicitly setting a labelRotation value?
