Descendants chart

This module provides an SVG descendant chart for the webtrees genealogical application. It is capable of displaying up to 25 generations of descendants from an individual.

But beware, if you select too many generations, it may take a while and even slow down your system significantly.

In addition to the descendants, the respective spouses are also displayed for a person. The display can be deactivated via the configuration form so that only the direct descendants are displayed.

Installation

Requires webtrees 2.2.

There are several ways to install the module. The method using composer is suitable for experienced users, as a developer you can also use git to get a copy of the repository. For all other users, however, manual installation is recommended.

Manual installation

To manually install the module, perform the following steps:

1. Download the latest release of the module.
2. Upload the downloaded file to your web server.
3. Unzip the package into your modules_v4 directory.
4. Rename the folder to webtrees-descendants-chart

If everything was successful, you should see a subdirectory webtrees-descendants-chart with the unpacked content in the modules_v4 directory.

Then follow the steps described in configuration and usage.

Using Composer

Typically, to install with composer, just run the following command from the command line, from the root of your Webtrees installation.

composer require magicsunday/webtrees-descendants-chart --update-no-dev

The module will automatically install into the modules_v4 directory of your webtrees installation. To make this possible, the "magicsunday/webtrees-module-base" package is used. Approval within Composer may be required here to authorize the execution of the package.

To remove the module run:

composer remove magicsunday/webtrees-descendants-chart --update-no-dev

composer require magicsunday/webtrees-descendants-chart:dev-main --update-no-dev

Using Git

If you are using git, you could also clone the current main branch directly into your modules_v4 directory by calling:

Then follow the steps described in configuration and usage.

Configuration

Go to the control panel (admin section) of your installation and scroll down to the Modules section. Click on Charts (in subsection Genealogy). Enable the Descendants chart custom module (optionally disable the original installed descendant chart module) and save your settings.
