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?

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!
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,
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 Offray,
CompositeShape are not the right thing to use here.
I have just created a new class Epicycle, subclass of Object.
I have added the method on that class:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
epicycleAt: diameter inView: v
| circle ex1 ex2 line retweets reach radious origin background els |
background := (RTBox new color: Color transparent) element.
v add: background.
origin := (0@0).
radious := diameter / 2.
circle := (RTEllipse new size: diameter; borderColor: Color black; color: Color
transparent) element.
ex1 := RTBox element.
ex2 := RTBox element.
circle translateTo: origin.
ex1 translateTo: ((radious negated @ 0) + circle center).
ex2 translateTo: (radious @ 0) + circle center.
line := (RTLine new; color: Color black) edgeFrom: ex1 to: ex2.
v 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.
els := RTGroup with: retweets with: reach with: circle with: ex1 with: ex2.
RTNest new on: background nest: els.
^ background
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
I am then able to write:
-=-=-=-=-=-=-=-=-=-=-=-=
v := RTView new.
e1 := Epicycle new epicycleAt: 50 inView: v.
e2 := Epicycle new epicycleAt: 100 inView: v.
e1 @ RTDraggable.
e2 @ RTDraggable.
e2 translateBy: 10 @ 100.

Hi Alexandre :),
Thanks! Now is working pretty well. My modified method was:
~~~~~~~~~
myClass>>labeledCircleSized: diameter upLabel: label1 downLabel: label2
inView: v
| circle ex1 ex2 line retweets reach radious origin background els |
background := (RTBox new color: Color transparent) element.
v add: background.
origin := (0@0).
radious := diameter / 2.
circle := (RTEllipse new size: diameter; borderColor: Color black;
color: Color transparent) element.
ex1 := RTBox element.
ex2 := RTBox element.
circle translateTo: origin.
ex1 translateTo: ((radious negated @ 0) + circle center).
ex2 translateTo: (radious @ 0) + circle center.
line := (RTLine new; color: Color black) edgeFrom: ex1 to: ex2.
v add: circle; add: line.
retweets := (RTLabel text: label1) element.
reach := (RTLabel text: label2) element.
v add: retweets; add: reach.
retweets translateTo: (0 @ -12) + circle center.
reach translateTo: (0 @ 12) + circle center.
els := RTGroup with: retweets with: reach with: circle with: ex1 with: ex2.
RTNest new on: background nest: els.
^ background
~~~~~~~~~
Some minor questions left:
- Why composite shape was not the right thing to use and how can a
newbie could differenciate which strategy to use?
- A sytle question "labeledCircleSized: upLabel: downLabel: at:" seems
descriptive to me, but I don't know if has the proper style for a method
name. I can read Smalltalk with Style to look at it, now that I know
more about the environment, but advice of seasoned smalltalkers would
help a lot in getting proper style also.

I have just created a new class Epicycle, subclass of Object.
I have added the method on that class:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
epicycleAt: diameter inView: v
| circle ex1 ex2 line retweets reach radious origin background els |
background := (RTBox new color: Color transparent) element.
v add: background.
origin := (0@0).
radious := diameter / 2.
circle := (RTEllipse new size: diameter; borderColor: Color black;
color: Color transparent) element.
ex1 := RTBox element.
ex2 := RTBox element.
circle translateTo: origin.
ex1 translateTo: ((radious negated @ 0) + circle center).
ex2 translateTo: (radious @ 0) + circle center.
line := (RTLine new; color: Color black) edgeFrom: ex1 to: ex2.
v 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.
els := RTGroup with: retweets with: reach with: circle with: ex1 with:
ex2.
RTNest new on: background nest: els.
^ background
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
I am then able to write:
-=-=-=-=-=-=-=-=-=-=-=-=
v := RTView new.
e1 := Epicycle new epicycleAt: 50 inView: v.
e2 := Epicycle new epicycleAt: 100 inView: v.
e1 @ RTDraggable.
e2 @ RTDraggable.
e2 translateBy: 10 @ 100.
v
-=-=-=-=-=-=-=-=-=-=-=-=
Let me know how it goes.

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

https://www.iam.unibe.ch/mailman/listinfo/moose-dev 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

Thanks! Now is working pretty well. My modified method
was:
Excellent!
Some minor questions left:
- Why composite shape was not the right thing to use and how can a newbie could
differenciate which strategy to use?
I think that the problem is the lack of good documentation. With all this time, I am
convinced that composite shapes are good at naming elements. E.g., putting a name on top
of circle or a square.
As soon as you want to glue two or more object
- A sytle question "labeledCircleSized: upLabel:
downLabel: at:" seems descriptive to me, but I don't know if has the proper style
for a method name. I can read Smalltalk with Style to look at it, now that I know more
about the environment, but advice of seasoned smalltalkers would help a lot in getting
proper style also.
You may want to use a factory object to configure its creation :-)
Will you be at Esug by the way? We will have a camp about Roassal.

you simply have to send #focusOnCenterScaled to the Trachel canvas. Consider the following

My bad. Again a picture is worth a thousand of words :-). So I have send
you some pictures of what I mean:
- Graphic 1:

The graphic 1 is just my grafoscopio notebook where I'm testing your
help notes. The code to produce the graphic at the right most panel is
published at: [1] http://ws.stfx.eu/4AZSKR2NH7AO. The graphic 2 is an
exportation of that graphic as a png edited by hand with the things I
would like to add. Some labeled boxes with color conventions (white:
days, light gray: weeks, gray: months) and this custom ruler scale at
the bottom of the graphic. I have read the visualization composition
chapter but If I remember well, you shared with us some other way to put
conventions on a graph, which seem easier. How can I add the custom
ruler and labeled convention boxes?
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?
Another strange thing happen when I was making this test: The circular

gray or all black. See video example at: [3]

Ohh ok! Bookmarked. Surely in the future, the Dataviz package will
contain some "Visual helpers" with this kind of custom forms, like the
labeled circle, which can be used for several objects in their custom
visualizations. I was wondering if the name "labeledCircleSized:
upperLabel: bottomLabel: at:" was a good one and follows the
Smalltalk-ish good style rules.

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.
~~~~~~
Cheers,
Offray
