Nodes size: a very strange problem #1443

Hi,

I’m trying to create a very simple graph on Gephi, but there’s a very strange thing happening.

I’m importing a csv file for the nodes, with only 3 columns: id (string), label (string) and relevance (integer, with numbers varying just from 1 to 3).

My goal is to have the nodes size matching the values from the 'relevance' column of the csv file, just picking this attribute in appearance > nodes > size > attribute.

When I import a csv file like this

id, label, relevance
1, red, 1
2, green, 2
3, blue, 1
4, yellow, 3
5, grey, 3
6, pink, 2
7, black, 1
8, white, 3
9, orange, 2

everything is fine.

But, when I add just one more line in the csv file, like

10, brown, 3

the attribute ‘relevance’ doesn’t appear anymore in appearance > nodes > size > attribute.

If I put this 10th line manually on the Data Laboratory, it’s OK. But I really need that this values can come directly from the csv file.

Can anyone tell me why this is happening?

I'm using the Gephi version 0.9.1.

Thank you!

I'm having similar problems where a float field in a gexf file I've created doesn't appear in nodes > size > attribute. It does appear in nodes > color > attribute.

I'm having the same issue

I can confirm this bug for my setup, tried all different import formats for the attribute (which is an integer in my case),

Gephi won't recognize this attribute for node sizing / text label sizing.
It is correctly recognized in Node Color, and in the filters.

I tried importing to different types, and forcing "create new nodes..." but behaviour remains. My test graph has 235 nodes.

addit info:
Java: 1.8.0_73; Java HotSpot(TM) 64-Bit Server VM 25.73-b02
System: Windows 10 versión 10.0 que se ejecuta en amd64; Cp1252; es_AR (gephi)

PS: title on this issue should be changed to better reflect the issue after two more tests in my view
1.does this only happen for csv ?
2.when nodes >10 ?

This is bug #1459

Explanation: Gephi now tries to auto-detect wether the column should be ranking or pratition

@cladelpino

semi OT: that should be very hard to "auto-detect" consistently.

Why not ask the user with a tooltip explaining diff between rank/partition (which anyone serious with networks should know) during import ?

Yeah that will be changed/fixed in 0.9.2, it should be possible to use any column with both modes in appeareance.

Duplicate of #1459 - we'll fix this auto-detect issue and make the choices more explicit in 0.9.2
