[Qgis-user] Atlas by year

[Alexandre Neto]

You need to create a layer, with a column called year, with each year in a
row. The layer does not need to have a geometry. Use that layer as the
coverage layer for atlas.

For the layer you want to filter by year, create a rule-based symbology,
and use the following rule/expression:

attribute(@atlasfeature, 'yea
r') = "year"

This compares the current atlas feature field year, to the layer year
column, and renders the features only if the years match.

Hope it helps.
