The behavior is still odd. If I change the previous code to 10 visualize
ten arcs:
view := RTView new.
shape := RTArc new
innerRadius: [ :i | i *50];
externalRadius: [ :i | (i * 50) + 4];
alphaAngle: 45;
betaAngle: 135;
color: Color black.
elems := shape elementsOn: (1 to: 10).
view addAll: elems.
label := RTLabelled new text: #yourself.
label left.
elems @ label.
view
The result is this:
I think this happens because it is trying to put the label at the
left-center of the arc (encompassing rectangle?). There is a way to put it
at the left bottom?

It is not always what one wants to achieve, as you demonstrated on your
example.

Looks somewhat odd, still, when you change the angles:
view := RTView new.
shape := RTArc new
innerRadius: [ :i | i *50];
externalRadius: [ :i | (i * 50) + 4];
alphaAngle: 315;
betaAngle: 45;
color: Color black.
elems := shape elementsOn: (1 to: 2).
view addAll: elems.
label := RTLabelled new text: #yourself.
label left.
elems @ label.
view

If you use the angles 270 and 90 (in that order), you get:

Thanks Milton! I was on this issue, but you were
faster than me :-)
Good job!

Hi
There was a problem in #encompassingRectangle in TRArcShape, try again
with the last version of Roassal

Following this, I tried to add labels to the arcs
but It is not working
as I expected. My code:
view := RTView new.
shape := RTArc new
innerRadius: [ :i | i *50];
externalRadius: [ :i | (i * 50) + 4];
alphaAngle: 45;
betaAngle: 135;
color: Color black.
elems := shape elementsOn: (1 to: 2).
view addAll: elems.
label := RTLabelled new text: #yourself.
label left.
elems @ label.
view
and the results is the attached image.<labels.png>
I want the labels to be at the left of the arc line. Maybe I'm doing
something wrong? any ideas?
Bests,
Miguel

I want to add labels first, after that I'm
going to publish a video. :)
