Dear Alexandre,

thanks for your initial version of the script.
As promised, here is the adapted version of what I basically would like to achieve:

Inline image 1

=======
"configuration"
spaceBetweenLine := 350.
lineHeight := 250.

"data"
columns := #(
#('One' 'Two')
#('Ten' 'Eleven' 'Twelve' 'Thirteen' 'Fourteen' 'Fifteen') ).
values := #( #(1 3 4 5 6) #(2 3 5) ).

numberOfColumns := columns size.
columnHeight := columns reduce: [ :c1 :c2 | (c1 size) max: (c2 size) ].

v := RTView new.
label := RTLabel text: [ :t | t ].
label color: (Color red alpha: 0.3).

"draw labels"
setOfElements := OrderedCollection new.
1 to: numberOfColumns do: [ :i | | t labels |
t := OrderedCollection new.
labels := label elementsOn: (columns at: i).
labels doWithIndex: [ :element :index |
t add: element.
element translateTo: 
(i * (spaceBetweenLine - 1)) @
(index * lineHeight / columnHeight).
v add: element
].
setOfElements add: t.
].

"draw lines"
2 to: numberOfColumns do: [ :column |
values doWithIndex: [ :setOfValues :index |
setOfValues do: [ :toIndex |
line := (RTLine new color: (Color red alpha: 0.2)) 
edgeFrom: ((setOfElements at: (column - 1)) at: index)
to: ((setOfElements at: column) at: toIndex).
v add: line
].
].
].
v
=======

Now it only needs to be made a bit prettier (e.g. starting the lines at the edges of the label, not in the middle; make it deal correctly with multiple columns; ...).

Thank you very much,
Manfred

Hi Alexandre,

thanks for the fast response and the nice script.
I'll see if I can use it to produce the graph I'd like to have.

Best,
Manfred

Hi Manfred,

The parallel coordinates is indeed easy to obtain in Roassal.

Here is a short example:
-=-=-=-=-=-=-=-=-=-=-=-=
"Configuration"
maxValue := 40.
spaceBetweenLine := 50.
lineHeight := 250.
numberOfColumns := 10.
numberOfLines := 200.

"Script"
values := OrderedCollection new.
numberOfLines timesRepeat: [ 
t := OrderedCollection new.
numberOfColumns timesRepeat: [ t add: maxValue atRandom ].
values add: t.
].

v := RTView new.
setOfElements := OrderedCollection new.
1 to: numberOfColumns do: [ :i |
t := OrderedCollection new.
values do: [ :setOfValues |
e := (RTEllipse new color: (Color red alpha: 0.3)) element.
t add: e.
e translateTo: 
(i * (spaceBetweenLine - 1)) @ 
((setOfValues at: i) * lineHeight / maxValue) asFloat.
v add: e.
].
setOfElements add: t.
].

2 to: numberOfColumns do: [ :column |
t := OrderedCollection new.
values doWithIndex: [ :setOfValues :index |
line := (RTLine new color: (Color red alpha: 0.2)) 
edgeFrom: ((setOfElements at: (column - 1)) at: index) to: ((setOfElements at: column) at: index).
v add: line.
].
].
v
-=-=-=-=-=-=-=-=-=-=-=-=

Best would be to define a new builder to allow for easy configuration. It would be easy to add colors

Cheers,
Alexandre

Hi everyone,

some time ago I saw a diagram consisting of two columns of words and lines showing associations between the words in both columns.
It looked similar to the "parallel coordinates" diagram from this link: http://homes.cs.washington.edu/~jheer/files/zoo/ but with only two columns.

Now, I am not sure if I saw this in an email on a Pharo or Moose list and wanted to ask if it is already possible to create such diagrams with Roassal.

Thank you very much,
Manfred
