This menu brings up several viewing options:
Topology only: This displays the tree in the form of relationships among the taxa , ignoring the branch lengths.
Root on Midpoint: This roots the tree on the midpoint of the longest path between two taxa.
Arrange Taxa: This allows you to arrange the taxa in the tree based on the order of taxa in the input data file or to produce a tree that looks “balanced.”
Tree/Branch Style: This allows you to select the display of the tree in one of three styles: Traditional, Radiation, or Circle. For Traditional, there are three additional options: Rectangular, Straight or Curved.
Show/Hide: This allows you to display or hide the following information: taxon label, taxon marker, statistics (e.g., bootstrap values), branch lengths, node ids, divergence times (for timetrees), data coverage (for timetrees) or scale bar.
Fonts: This allows you to choose features such as font type and size for information, including the taxon label, statistics, and scale bar.
Options: This brings up the Option dialog box, which provides control over various aspects of the tree drawing, including individual branches, the taxon names, and the scale bar.
