Hi Alexandre,
Thanks for your answer and sorry for my late one. Only until today we
return to our workshops (Hackerspace is small and was kind of crowded
previous weekend).
I have tested your code and produced some minor changes at [1]
[1] http://pastebin.com/wmF2JUZn
I have even created a composite shape (just a circle with a line in the
middle) with this code:
~~~~~~~~~~~~~~~~~~~~~
MyClass>>epicycleAt: center withSize: diameter
"Creates a little epicycle with an horizontal line at the middle.
Future helper for silence maps."
| epicycle circle ex1 ex2 line "retweets reach" radious |
radious := diameter / 2.
epicycle := RTCompositeShape new.
circle := (RTEllipse new size: diameter; borderColor: Color black;
color: Color transparent) element.
ex1 := RTBox element.
ex2 := RTBox element.
circle translateTo: center.
ex1 translateTo: ((radious negated @ 0) + circle center).
ex2 translateTo: (radious @ 0) + circle center.
line := (RTLine new; color: Color black) edgeFrom: ex1 to: ex2.
epicycle add: circle; add: line.
"retweets := (RTLabel text: 5) element.
reach := (RTLabel text: '3.1k') element.
v add: retweets; add: reach.
retweets translateTo: (0 @ -12) + circle center.
reach translateTo: (0 @ 12) + circle center."
^ epicycle.
~~~~~~~~~~~~~~~
But I don't know how to add this composite shape to a view. All examples
in composite shapes are kind of difficult and require creating some kind
of collection and then using addAll on the extraction of the members of
that collection. So, for a better understand on how composite shapes
work, could you please help me on how to create a simple composite shape
(a circle with a horizontal line) and show it in a view?
About the variation point of the visual element, it should be mainly the
center where it is located, and eventually the color.
Thanks,
Offray

Hi!
Well, it all depends what the circle actually mean.
You can simply draw it like that:
v := RTView new.
circle := (RTEllipse new size: 80; borderColor: Color black; borderWidth: 0.014; color:
Color transparent) element.
ex1 := RTBox element.
ex2 := RTBox element.
ex1 translateTo: -40 @ 0.
ex2 translateTo: 40 @ 0.
line := (RTLine new width: 2; color: Color black) edgeFrom: ex1 to: ex2.
v add: circle; add: line.
lbl1 := (RTLabel text: 5) element.
lbl2 := (RTLabel text: '3.1k') element.
v add: lbl1; add: lbl2.
lbl1 translateTo: 0 @ -20.
lbl2 translateTo: 0 @ 20.
v
But I am sure this is not what you want. How many circle do you plan to have? What are
the variation point of a visual element? Color? Size?
A proper implementation will likely be based on a dedicated builder.
Cheers,
Alexandre

Hi Alexandre :),
We're trying to create, programmaticaly in Roassal, something like the attached image
(which, by the way was created with the powerful DrGeo). Forget about the points in red.
I only want to create a circle with a horizontal line in the middle and two text on each
half. Eventually I would like to change the contrast of the text with the background of
the circle's filling, but that could be a second exercise.
Cheers,

Hi Offray!
I am not sure to understand. How we can help you?

Hi,
With some friends, we're playing with the idea of using epicycles [1] for a
visualization. So far, so good and we have some beta code script at [2]. We would like to
put a pair of numbers inside the epicycle. So the question is: How can we add a horizontal
line wich divides the epicycle in the middle and how can we put a number on each part?
