Please email us (Evolgenius Team) if you have any questions; attach your datasets and trees if necessary.
Branch colors will be applied to tree branches.
Similar to pie charts, multiple datasets for branch colors can be uploaded to a tree, but only one can be shown at a time.
Here is an example:
Supported Key-Value pairs for branch colors:
| Key (case insensitive) | Value | Description |
|---|---|---|
| !Groups or !LegendText | comma separated text | Legend texts; for example 'group_a,group_b,group_c' |
| !LegendStyle or !Style | rect or circle or star | shapes to be plotted before the legend texts; default = rect |
| !LegendColors or !Colors | comma separated color codes or names | colors to be applied to the shapes specified by LegendStyle; for example 'red,green,yellow' ; note the number of colors should match the number of legend fields |
| !Title or !Legend | text | title of the legend; default = name of the dataset |
| !ShowLegends | 0 or 1 | 0 : hide legends; 1 : show legends |
| !opacity | float number between 0 to 1 | opacity of the dataset |
Data are usually tab-delimited three-column texts, with the third column optional. Let me use the tree below to illustrate the usage of the data:
(chicken,((mouse,rat),(chimp,human)));
- first column: the location the first column dictates where the data to be plotted. It usually contains the name of a leaf node, or two leaf names separated by a ','.
- one single leaf name dictates that the data will be plotted on / next to / under the leaf or the branch connecting directly to the leaf node
- two leaf names, on the other hand, dictates that the data will be displayed on the branch representing the last common ancestor of the two leaf nodes
For example:
chicken
mouse,human
- second column: color to be applied
For example:
chicken green
mouse,human blue
- third column: optional commands to change the default behavior of current line
By default, the color will only apply to the specified branch; for example:
## branch color/ styles
human red
By adding a third column, the default behavior can be changed. Here is a list of choices of this column:
| Option (case insensitive) | Description |
|---|---|
| ad | apply color to all descendants |
| prefix | apply color to all branches connecting leaf nodes whose name starts with the string specified by the first column |
| suffix | apply color to all branches connecting leaf nodes whose name ends with the string specified by the first column |
| anywhere | apply color to all branches connecting leaf nodes whose name contains the string specified by the first column |
| toroot | apply color to all branches connecting the leaf node and parent nodes all the way to the root |
See the examples below.
Example 1, 'ad':
## branch color
human,mouse red ad
Example 2, 'prefix':
ch red prefix
Example 3, 'suffix':
n red prefix
Example 4, 'toroot':
## branch color from specified leaf node to the root
human red toroot
Evolview supports collapsing at internal nodes; collapsed nodes are treated as leaf nodes. It is therefore very straightforward to add branch color to a collapsed tree. See here for more information.
