graphical user interface for setting legend
legend = select_legend (legend)
Select or edit a legend; the active item is indicated and can be changed with button #. Edit maker specs with button marker and taxon name with button taxon. Edit the sequence with buttons v and ^, insert with >, remove with x. The sequence matters if taxa are not mutually exclusive and some markers will be plotted on top of each other.
- legend: optional (n,2)-matrix with markers (5-vector of cells) and taxa (string)
- legend: (m,2)-matrix with markers (5-vector of cells) and taxa (string)
Press any key when done. Calls select_marker to edit markers.
