Charts and Graphs

Ampache8 draws charts with goat1000/svggraph (LGPL-3.0). It's a normal, non-dev dependency, so a release download works with nothing extra to install, and there's no ext-gd requirement. Graphs render as SVG instead of PNG, so they scale to the page and stay sharp on a high-dpi screen.

statistical_graphs defaults to "true". Set it to "false" in your config if you want to skip the graph queries entirely, e.g. on a very large catalog:

; DEFAULT: "true"
statistical_graphs = "false"

The rest of this page covers Ampache7, which still uses the older, optional szymach/c-pchart library described below.

Ampache7: an optional GPLv3 charting library

Ampache7 uses a GPLv3 library for generating graphs szymach/c-pchart

Due to some issues around the license for the original library ampache/issues/1515

It has been decided to only provide a composer file containing 100% free software. That way it allows users the option of installing the package while not affecting the default install.

Installing non-free packages in Ampache

If the graphs and charts are important to you you can do the following.

To add the missing lib you can cd to the Ampache folder and run the following command.

  cd /var/www/html/ampache
  sudo -u www-data composer require szymach/c-pchart "2.*"

Disable non-free packages in Ampache

To remove c-pchart just change 'require' to 'remove'.

composer remove szymach/c-pchart
