Other replies to this message seem to assume that Joe wants to plot an
ellipse, which effectively renders it as a series of line segments. I
interpret Joe's question as meaning he wants to find a way of rotating the
graphics primitive for an ellipse, Circle[{x, y}, {r1, r2}]. I don't know of
any way to do this -- it seems you are stuck with ellipses whose major and
minor axes are parallel to the display coordinate axes.
