Clara:
Filtering the Vertices worksheet using Excel's filtering features won't work in NodeXL. That's because the filtered vertices are still part of some edges in the Edges worksheet, and so NodeXL will continue to show all the vertices and their edges in
the graph pane when you refresh the graph.
But all is not lost. To get rid of the vertices and their edges in the graph pane, set the vertices' "Visibility" cells on the Vertices worksheet to "Skip." For more information about what the "Visibility" column does, hover your mouse over the
"Visibility" column header. I'll paste the popup message after my signature.

Show if in an Edge
Show the vertex when the graph is refreshed if it is part of an edge. Otherwise, ignore the vertex row. This is the default.
Skip
Skip the vertex row and any edge rows that use the vertex.
Hide
If the vertex is part of an edge, use it when laying out the graph but then hide it. Otherwise, ignore the vertex row.
Show
Show the vertex regardless of whether it is part of an edge.
Formulas
If you are using Excel formulas to compute the visibilities, you may find it helpful to use the numerical options instead of text:
1 = Show if in an Edge
0 = Skip
2 = Hide
4 = Show
Pasting
If you want to paste values into this column, do not use the standard Paste command (CtrlV). The standard Paste command removes the dropdown lists from the column. Instead, use Home, Paste, Paste Values in the Excel Ribbon.
