How to reduce the size of an edge ?

[lug031]

Hello,

Sorry for this dummy question but, my graph contains edges with weight values between 1 and 3. The size of the on the graph is enormous for value 2 and 3. If I use the scale in edges tab, I reduce the size of all the edges and those with weight equal to 1 become quite invisible when those with value 2 and 3 have an "acceptable" size.

How can I set a value to display edges with weigth=2 and weigth=3 only 2 or 3 times the size of those with weight=1 ?
Or could it be possible to set a range to display nodes? With Ranking, I can only change label size or edge color ?

Thank you

This is a limitation in Overview. You can have better tuning on Preview.

my graph has no partition or ranking functions active on the edge level and yet there are large edges exactly as described in the image above.

what controls the thickness of these edges? What does the thickness represent?
