One of the layers has around 5000 attribute entries, based on a CSV file of species records. All the features are of course shown on the map layer. How can I select a specific class of features so that only they appear on a map, so that for example a distribution map for a species can be generated. I have tried "Advanced Filter (Expression)" so that the Attribute Table shows only the required species, but it still shows all the attributes on the map layer.
I am using QGIS 2.10.1.
