Add Timeline

Add Timeline

Gephi supports "dynamic graphs" which have a time dimension. Dynamic graphs are assigned a timeline that can be used to provide an animated playback over time:

To support these timelines, ethgraph adds a field called appearanceIndex to the graphml extract. The appearanceIndex is an integer running from 0 to N, where N is the lastmost movement in the data extract.

To add a timeline, use Gephi's data laboratory and these steps:

The above shows how you:

1. Click "Data Laboratory" button.
2. Clicking "Merge columns".
3. On the resulting popup, pick the appearanceIndex field.
4. Identify the field as a "time interval".
5. On the "Create time interval" screen, the "End time column" should be blank (because once appeared, nothing should disappear). The "Default end time" should be the largest appearanceIndex in the whole data set.
6. Once the above new field is added, an "enable timeline" button appears. Click the button to add a timeline.
7. Timelines can now be replayed. The default selection is the whole of time, so initially, pressing the play button does nothing. You first have to reduce the default selection of every frame, as shown in the above animation.
