Hi,
Remember to correctly structure the whole gexf file, also declaring it as dynamic.
I attach a correct gexf file for your network.

Below is the format of the source data trace:

TimeInstant #Node_x #Node_y EventType={Connection} Value={0, 1},
where TimeInstant is expressed in seconds and starts from 0.
For example:
12 12 13 Conn 1 - meaning a connection was established
18 12 13 Conn 0 - meaning the connection is down
Connections are symmetric, meaning the graph is undirected.

The corresponding gephi:

I there anything wrong ?

Thnx in advance

Thank you for the response,

I managed to format the trace i had in the required format as specified in the link you gave me.
To be concise:
" The dynamic graph is composed of the node declaration part: node_id and label,
and the edge/connections part where i specify the start and end time.
The nodes are in the trace the entire time, in gephi terminology they have a lifetime of -+ infinity,
while the edges should come and go as dictated by the time intervals "

Unfortunately, the timeline is not working as i should and i cannot tell why this is happening ?

Any insight ?

Again thnx.

Hi,
That's perfectly possible.
Your edges would have the time interval.

Check this https://wiki.gephi.org/index.php/Import_Dynamic_Data

Visualize Contact Traces

2013-04-30T20:34:19+01:00

Hello,

for research purposes I wanted to use Gephi to visualize and inspect the dynamic evolution of some human contact traces.

Is this possible ?

To provide more info about the format: for each pair of nodes I have the intervals they are in contact with each other.

Thank You in advance.
