    Hello -

    System: Win 7 Pro x64, Tulip v4.2

    I have a graph which is the result of equal value clustering followed by quotient clustering. I want to set the sizes of the meta edges, but am unable to do so. So far I have

    1) manually altered the sizes of the original existing meta edges
    2) deleted the existing meta edges and written a Python script to create new edges with a new local parameter to control a metric value that I have used in the metric mapping plugin.
    3) deleted all meta edges and manually created new edges and then changed their size.

    Nothing has worked. In every case I have also turned on and off the various scene rendering settings related to edges to see if that would change the graph appearance. Although the color interpolation performs as expected, none of the other settings seemed to affect the meta edges.

    I suspect that I'm missing some elementary switch/parameter/fact and would really appreciate some guidance. :-)

    Thanks!

    David

    David,

    the size of edges is not taken into account if
    'Enable size interpolation' is set in the the 'Scene' panel of
    the node link diagram view; so you must check it is not.
    If possible, I will be interested to have your graph before you apply
    quotient clustering because I do not understand why the 'edge cardinality'
    value is set to 0 for all edges

    Hi Patrick -

    I did turn off the Enable Size Interpolation flag in the Scene Panel of the Node Link Diagram View and then clicked on Apply Changes, but that didn't make any difference.

    I've attached the tlpx file for this project. In the graph hierarchy, the equal value clustering was applied to the field Subtitle in the graph "CloneOfParent Groups > 3 w Equal Value Clustering" resulting in the 10 subgraphs below it. I then applied quotient clustering to that same graph resulting in a new graph named "Quotient of CloneOfParent Groups > 3 w Equal Value Clustering". I'll be very interested to learn if you discover anything that I've done incorrectly. :-)

    Thank you again for all of your help.

    David

    Hi David,

    It seems that there is a strange behaviour when drawing
    the edges of your graph. Like you, I was unable to visually
    change the size of the edges. More investigation is needed.

    Thanks for looking into this, Patrick. At least I know it wasn't something obvious that I was doing wrong. :-) I'll wait to hear back from you.

    Cheers,
    David

    Hello Patrick -

    Just wondered if you'd had a chance to identify the cause of the problem I'm having with my graph. I've been unable to work around it. Thanks.

    Cheers,
    David

      Hello David,

      the problem was not in your graph, but I extracted a minimal
      example from it which allowed us to reproduce and finally fix a
      bug in the rendering of edges.
      The fix will be available in the next Tulip 4.3 version which, I hope,
      will be released before the end of June.
