show_edges — highlights a set of edges
show_edges(p [,sup]) show_edges(p ,sup=value) show_edges(p ,leg=value) show_edges(p ,sup=value,leg=value)
vector of arc numbers (directed graph) or edge numbers (undirected graph)
string, superposition flag. The default value is
'no'.
string, data field to be displayed. The default value is
'nothing'.
show_edges highlights the set of arcs or edges
p of the displayed graph in the current edit_graph window (see netwindow). If the optional argument
sup is equal to the string 'sup', the highlighting is
superposed on the previous one.
If leg is equal to 'number' the edge numbers are
also drawn.
If leg is equal to 'name' the edge names are also
drawn.
If leg is equal to one of the edges data fields
'name' the corresponding values are also drawn.
