Trees in GeneWeb
|Language:||English • français|
GeneWeb provides a powerful tool to build and display trees. Ascendant/Descendants menu offers a rich set of options to display ascendances or descendances as lists or trees, with or without spouses, with or without images, ...
The templm template offers similar functions under the headings "Ascendants", "Siblings", "Descendants", as well as under the "Relations" heading. The latter displays the tree between the selected eprson ans all its relations (godfather, godmother, godchildren, persons to which he or she was witness at some event. Each event in turn offers a button to display the relation between the person and its witnesses.
Beyond these predefined or parametrisable trees, it is possible, with some effort and perseverance, to construct much richer trees. An example has been provided by Michael White:
This tree is the result of the merge of all paths between the root and a selected set of sosa illustrating the level of inbreeding in the ancestry.
Note on this example that certain persons are displayed multiple times (for instance Flora M. Maxwell, the mother of the root), due to the fact that it is not possible to reorganise this graph in the plane without crossing lines.
Building such a tree is achieved in the following fashion:
http://localhost:2317/base?;m=RLM;followed by a succession of
i1+2p=index1+2p;i2+2p=index2+2p;p vaying from 0 to n (limit?).
- index1+2p is the index of a person, as defined by GeneWeb (see Managing namesakes).
- one can associate a text to each person through the parameter
t1+2p=free text;. This text will be displayed boldface next to the name.
The graph is the result of the union of all ascendance path between the couples designated by
At this day, paths through marriage are not taken into account.
