Figure 15.6: The tree layout can be adjusted in the Side Panel. Five different layouts can be
selected and the node order can be changed to increasing or decreasing. The tree topology and
node order can be reverted to the original view with the button labeled "Reset Tree Topology".
Cladogram is a rooted tree without branch lengths which is useful for visualizing the
topology of trees.
Circular Phylogram is also a phylogram but with the leaves in a circular layout.
Circular Cladogram is also a cladogram but with the leaves in a circular layout.
Radial is an unrooted tree that has the same topology and branch lengths as the
rooted styles, but lacks any indication of evolutionary direction.
• Ordering The nodes can be ordered after the branch length; either Increasing (shown in
figure 15.7) or Decreasing.
• Reset Tree Topology Resets to the default tree topology and node order (see figure 15.7).
• Ordering The nodes can be ordered after the branch length; either Increasing (shown in
figure 15.7) or Decreasing.
• Reset Tree Topology Resets to the default tree topology and node order (see figure 15.7).
• Fixed width on zoom Locks the horizontal size of the tree to the size of the main window.
Zoom is therefore only performed on the vertical axis when this option is enabled.
• Show as unrooted tree The tree can be shown with or without a root.
15.3.3
Node settings
The nodes can be manipulated in several ways.
• Leaf node symbol Leaf nodes can be shown as a range of different symbols (Dot, Box,
Circle, etc.).
• Internal node symbols The internal nodes can also be shown with a range of different
symbols (Dot, Box, Circle, etc.).
