[SOLVED] Suggested Time Value Scale?

[cpdiehl]

I'm attempting to use the new spreadsheet format to import a dynamic network into Gephi 0.8 beta. I've just finished creating a node file with time intervals. I imported that into Gephi just to see if I could see the node presence modulate over time as the visualization progresses. The problem is that when I press play, I see nothing happen.

Is there documentation that explains in more detail how to use the timeline controls and what sort of scale we should use for the time values? When I press play, I assume it steps forward in time at some interval? How does one define that interval?

Thanks, Chris

The time intervals need to be transformed using the Merge Column function:

You can also parse time intervals directly with the following syntax
<[1, 3]>

Eduardo, would that work with multiple blocks? For instance, if I have a link that is active in January and February and active again in July and August, could I write <[1,2],[7,8]> or do I need to write something that produces a custom GEXF, which is the only way I thought it was possible to have that kind of intervals.

[eduramiba]

Yes, you can parse time intervals like

Code: Select all

<[1,2];[7,9]>

for multiple blocks.

Sorry to be pedantic, but I'm not in a place to test this and I want to make sure I understand correctly, is it possible for me to pull this in from a database field formatted like that? If so, what variable type does the field need?

[eduramiba]

No problem

The column needs to have TimeInterval type so it can parse that syntax.
For other dynamic types the syntax is similar (see https://gephi.org/users/supported-graph ... preadsheet).
