The coordinates for Circle (and all patches) are in data coordinates. So the (300, 300) is relative to the values in the data itself. When adding a patch directly to a plot, however, the limits may not automatically update, so you may need to call axes.set_xlim or axes.set_ylim to adjust them to make the circle visible.
