Another possibility is not use this custom scale ruler and instead we will use some kind of arcs, but I would like to test different approaches to choose from. By the way testing the arcs approach (code at [2] http://ws.stfx.eu/EGZ9ZYULOR0 and graphic 3) I start to wonder if there is not a better way by having overlapping ellipsis with transparent background and custom colored borders. Is this possible?

By the way this code paints a totally gray circle, not a transparent one with a gray border:

~~~~~~
| weeksOrbit diameter v |

v := RTView new.
diameter := 55.
weeksOrbit := (RTEllipse new
                        size: diameter;
                        color: Color white;
                        borderColor: Color lightGray) element.
v add: weeksOrbit.
v.
