Orange Galerie.


No, it’s not about the color, nor about the french entreprise, it about the project “Orange” : Open source data visualization and analysis for novice and experts. Data mining through visual programming or Python scripting.


The Orange python environment have been enriched with widgets dedicated to UnderTracks (communication with data, visualisation, …).


Here are some of the analysis processes developped mixing UnderTracks Data and Operators within the Orange Interface.

Comparison between two judges :  hysteresisOrange

Processes (gallery)

Complex process. The first one is not the simplest, it is -essentially- a proof of concept: Process can be complex. demoARVSpaghetti


Linear process. The second one is the beginning of a long story: how to visualize the activity of students (linear process). sci_1


Data that are not student’s traces of interaction. The third one is an example of possible use of UnderTracks for another purpose: how to find and visualize differences between judges’ evaluation. hysteresisLog


A new idea. Different visualization to find the good one. ife


Linear process becomes a star. It’s a merge of the linear process and of the previous process. copex2
