I am fairly new to NodeXL and this seems like a pretty simple problem, but I am really having a hard time.
I am working with some bibliographic citation data showing co-authorship relationships among scholars in a certain field. The file I originally imported into NodeXL was the co-authorship list (an edge list with an author name in each of the two vertex columns,
and a number in the third column indicating the number of occurrences of co-authorship).
Now, I'd like to go back and add some authors who are also in the network, but have not co-authored, as unconnected vertices to this graph. I have manually entered them into the vertices sheet, but they do not appear in the graph. When I highlight the rows
with the new unconnected vertices and try to choose Lay out again> Lay out selected vertices -- that option is greyed out.
I'm guessing there is a filter (?) somewhere that is filtering out vertices with a degree of 0?
Or vertices are just being pulled from the edges list?
