Vertex Display Options

Jan 21, 2009 at 7:43 PM

A few display options that might be useful or possible:

Would be nice if the vertex radius could be automatically determined by the the number of connected edges (in and/or out degree). Vertices with many connections would display with a larger halo (vetex radius) than those with fewer connections.

Would be nice to have a display tag or label on a vertex that would show key metrics for the vertex such as the number of in/out edge connections.

Would be nice to able to control the label text color on vertices and make it different than the vertex shape color. (You can change the label fill but that option adds to the visual clutter for graphs with many vertices.)

Any or all of these possible using the "add your own" column?

You can do the first two things right now.  For the first, do the following:

* Tell NodeXL to calculate the In-Degree/Out-Degree or Degree graph metrics, depending on whether your graph is directed or undirected.  (Hover over NodeXL, Analysis, Calculate Graph Metrics for details on how to do this.)

* Select NodeXL, Graph, AutoFill Columns.

* Check the "Use AutoFill Columns" checkbox, and select In-Degree, Out-Degree, or Degree from the drop-down box to the right of "Vertex Radius."

* Click the Read Workbook button in the graph pane.

Voila, the Radius column on the Vertices worksheet gets autofilled with radii that are proportional to the degree metric you specified, and the vertices are sized accordingly.

For the vertex labels, do the same as outlined above, but in the AutoFill Columns dialog box select a metric for the Vertex Secondary Label instead.  The selected metric will appear next to each vertex when you click Read Workbook.

Ahhh.... thank you! I was looking for display controls in the options dialogue box. Didn't think to look within the Autofill.
