Smart color chooser for clusters

Post by seinecle » 01 Apr 2012 16:53

Hi,

I hope it's not too late to submit an idea for the GSoC:

simply, the idea is to integrate the "colors for data scientists" into the relevant functions of Gephi?

This tool would be very, very useful to generate coherent color palettes when partitioning a network in different node colors, according to the clusters they belong. As you know, the colors generated at the moment are generally not nice: you can have clusters colorized in very similar hues, making it hard to distinguish them. Manual corrections are possible but bothersome, and lead to a still imperfect result.

Website of "colors for data scientists": http://jiminy.medialab.sciences-po.fr/tools/palettes/ (by somebody not too unfamiliar to Gephi I believe :-))

This should be part of the Partition work planned for the 0.9 release. The partition module should be mostly rewritten (like we did for Ranking and Preview) for that release and we'll integrate this awesome work on palettes.

The R programming language offers a range of different color palettes that may also be useful. Off the top of my, colorbrewer is one, though originally intended for maps, I think... http://colorbrewer2.org/

The R ggplot2 library also provides a range of colour palette options eg http://learnr.wordpress.com/2009/04/15/ ... -palettes/

One thing I'd quite like to be able to do is select even random palettes but be able to specify something like pastel shades.

Being able to select from a range of palettes in eg the partition coloring panel would be really useful.

Hi guys,

Out of curiosity, did this ever happen? It would be great to have pre-set palettes for partitions, and even better if there was a way to save the association between node and color (such that they could be recolored for other analytical purposes, but then set back to the previous color scheme).

No the development haven't started on that yet. Can you please be more specific about what you mean with the association between nodes and colors? Thanks.
