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
