# Facets

Every report can have two or more Y, two X or more X, in this case we call this report faceted. Basically, it splits a chart and draws it for every variable as a facet. For example, you can create a chart that shows dynamic of cards creation by time for all your Trello boards.

What can we say about the above chart? It is clear that [Subnautica Development board](https://trello.com/b/yxoJrFgP/subnautica-development) has more cards created during all time and [Habitica board](https://trello.com/b/EpoYEYod/habitica) is almost dead from middle of 2016.
