However I have the same feeling that Clement posted. No dynamic attributes in the gexf file? (Can anybody confirm this?). The problem is that sometimes (many many times, especially in dynamic systems) the size and color attributes are used to represent other things, other information that cannot be extracted by any metric. For example that "metadata" or that "state variable" could be the incidence of a disease in a city, the number of people that visit an airport, the age of a person in a twitter network, or the participation coefficient of a node in a modularity algorithm different from the one implemented in gephi... whatever.
Therefore, is it possible to introduce the value of a dynamic attribute in the gexf file? Using spell maybe? Is there any other solution to represent the above-mentioned information in a dynamic graph using gephi???
This, along with Elijah HD videos, would be the definitive tool for visualizing dynamic processes in networks.
Best regards,
LJ.

You can use these data: http://www.sociopatterns.org/datasets/p ... -networks/
Or generate a dynamic random graph (File > Generate > Dynamic Graph Example)
In Ranking, select Degree of Nodes as a parameter and Color as the mapping target.
Enable the auto-transformation button just on the left of the Auto-apply button, then activate the Auto-apply button itself.
Now you can use the timeline to filter the dynamic graph over the time period you want. The color is updated in real-time.

"Dynamic visual attributes will be supported in the form of an evolution of the Ranking module, with an "auto-apply" option. That will allow to change color and size continuously when the graph is changing. So instead of defining a dynamic size parameter for node, you'll define a standard dynamic attribute attached to the node and use Ranking to code it as a size in real-time."
I have installed 0.8 beta but I do not have an "Auto-Apply" button, I have an Apply button...consequences on functionality...?
Can you provide a simple example gexf file with 2 nodes and an edge weight varying over time plus the steps of using the Ranking feature to display this variation with the Timeline?
Thank-you for your help.

I think I get it now:
- no dynamic viz attributes in the gexf file.
- that's because you don't need them: GEPHI takes a dynamic attribute in the gexf file and allows the user to visualize it.
[EDIT: yeah, but then it would be cool to be able to store the parameters one used for the visualization of this dynamic attribute, to be able to reproduce it later. Should it be the role of the Gephi file?]
Anyway, I can wait a few weeks, play with the new release and understand all that better!
Best,
Clement

I'm curious though: with this "apply continuously" option, are the resulting changes in size and color recorded in the corresponding gexf file, when exporting the graph?
I'm not sure I understand what you mean. If you have a dynamic column the ranking can use this column will be exported as well.Statistics:Posted by mbastian — 15 Sep 2011 16:06

I just notices that this thread had been expanded by new comments and grrreat news!
Honestly dynamic viz attributes is a giant leap - congrats and thx!

A early version of this feature has just been implemented in the trunk. You can test and give us your feedback

Dynamic visual attributes are currently not supported by Gephi. Wait for a future release!

I tried different ways to make the viz:size attribute dynamic, but none of them work:
CODE:
<node id="n1" label="n1" start="2005.0" end="2032.0"> <attvalues> <attvalue for="score" value="3" start="2005.0" end="2011.0"></attvalue> <attvalue for="score" value="2" start="2012.0" end="2016.0"></attvalue> </attvalues> <viz:size value="10.0" start="2005.0" end="2016.0"><viz:size value="20.0" start="2017.0" end="2032.0"></viz:size> <viz:position x="-329.90173" y="-218.28006"></viz:position> </node>CODE:
<node id="n1" label="n1" start="2005.0" end="2032.0"> <attvalues> <attvalue for="score" value="3" start="2005.0" end="2011.0"></attvalue> <attvalue for="score" value="2" start="2012.0" end="2016.0"></attvalue> </attvalues> <viz:size value="10.0" start="2005.0" end="2016.0"> </viz:size> <viz:size value="20.0" start="2017.0" end="2032.0"></viz:size> <viz:position x="-329.90173" y="-218.28006"></viz:position> </node>Also, I suppose that the viz:size attribute should be declared as a dynamic attribute at the beginning of the gexf file - but as it is a sepcial attribute (from the viz module), how do you do that?
Thx for your help!

I'd like to resize my nodes with the ranking function, according to an attribute which is dynamic.
=> it would give a time-stamped size to the node (the node would vary in size in time, following the values of the attribute).
As far as I can see, it can't be done for the moment. Could it be implemented?
(meanwhile, I'll try to work on my gexf file to make the viz: size attribute vary dynamically)
Best,
Clement
