Re: Is graph editing supposed to work in 0.7?

I've been thinking about simple combinations of attributes mostly, e.g. inlinks-outlinks &c. - mostly to generate attributes for visualization (node radius, color &c.).

So the current way is to create the appropriate attributes in the application that exports/generates the network?

Yes.

Are there any plans regarding formula-driven attribute creation (e.g. sqrt(inlinks))?

Yes, the Data Laboratory project plans to go much further in data manipulation, including
- Column add/remove/duplicate
- Basic formlula manipulation
- Transformations

How far would you need to use formula and transform your data ?

That would be rather useful, thanks for adding it to the list.

This is a missing feature, we could make it available in editing window and in data lab.

I edited the Ideas List

And one more "editing" question: Is it somehow possible to add node attributes?

Another editing-related issue: When I click the "edit node attributes" icon & then activate the "Drag" tool, moving nodes doesn't work any more.

In general, tool activation seems a bit buggy/non-intuitive. What does it mean for a selection mode/tool (?) (Mouse selection, Rectangle, Drag) and one of the other tools (Painter, Sizer &c.) to be active at the same time?

jbilcke, thanks a lot for the workaround!

Once I've finished my Launchpad registration (so many accounts ...), I'll enter the bug there.

Yes I confirm, there is a bug, no graph is shown until there is some edges in the graph. Could you please report the bug? Thanks

Hi,

it looks like this bug happens when a project is created and empty, or a graph is loaded but without any network (ie. no edge).

thus, until this bug is fixed, you can load a "dummy" gdf file to initialize Gephi. By example, create a "empty.gdf" document, containing these lines:

CODE:

nodedef> name VARCHAR,label VARCHAR0,A1,Bedgedef> node1,node2,label VARCHAR0,1,E

and load it in Gephi. You can now create nodes.

Be aware that the node size is 1.0 by default, which is very small, so you may need to zoom in, then scale the node (there is a tool for that, blue diamond icon).

The other solution is to select a bigger default node size, and edge weight.
You can do it here, in the toolbar just over the the visualization :

(here it shows edge weight, because I selected the Edge Pencil)

I've the same problem on Windows. Just seems that these tools are disabled for the moment... Unfortunately. (to be confirmed)

I create a new project and try to add nodes and edges; however, after selecting the appropriate tools (node pencil/edge pencil) in the toolbar and clicking around in the empty graph area, nothing happens.

Is there something I'm doing wrong?

Platform: I'm using OS X 10.5. The Java version (according to java -version) is 1.6.0_15.
