graph edge length

Posted by jay on Feb 08, 2008

The graph library is brilliant! Unfortunately though I'm having a little bit of trouble deciphering the descriptions on the webpage. Is there a way to manipulate the length of individual edges? I would like to increase the length between key nodes in the hopes that it will make my graph more legible.

Thanks in advance for any suggestions.

Admittedly, setting the length of individual edges is not possible right now, but it shouldn't be too difficult to implement, I'll have a look at it. Sounds like a useful feature to have.

Meanwhile, you can use the distance parameter when you create a graph object or the graph.layout.tweak() method to influence the layout algorithm.

Hi Jay, you can download the latest version. The graph.add_edge() command has a new optional edge parameter, and edge objects all have a length property which is 1.0 by default. If you increase or decrease this value, this individual edge will become longer or shorter.
