[SOLVED] //edges,dynamic graph, discontinued period of times
Posted: 01 Apr 2010 18:25
Hi there,
As I said I am discovering the joy of playing with dynamics.
Ok now my issue is having paralelle edges with different start and end dates.
To make it clear here is a sample :
See two edges with same sources and target but present only on 2007/01/20 and 2007/01/22.
All right I should use an other technic I guess ?
So here is the real question behind this :
How an edge has to be coded in gexf to be present or hidden at different dates which are not a continued period of time ?
Problem comes to the fact that start and end attributes allows only one period of times and not severals.
So no discontinued presence for edges possible becasue of paralell restriction.
Ok but Does the paralell restriction apply on all graph element ?
Can I for instance declare different attribute values for one attribute id with different start and end dates ?
in code that would be :
And when the attribute isn't set (from 2007-01-27 to 2007-02-13 and from 2007-03-20 to 2007-04-21 in my example) gephi could use default value ?
This is just a proposition.
To sum up my point :
how to make edges definition (presence or attribute value) change through time in non-continued period of time ?
thx for help

To make it clear here is a sample :
Code: Select all
<edge source="3369" end="2007-01-22" target="2949" weight="1" start="2007-01-22" id="133">
<attvalues>
<attvalue for="0" value="1"/>
</attvalues>
</edge>
<edge source="3369" end="2007-01-20" target="2949" weight="1" start="2007-01-20" id="131">
<attvalues>
<attvalue for="0" value="1"/>
</attvalues>
</edge>
