Individual Values Theme - Properties

A Theme which styles items, i.e. changes their Brush, Pen, and Symbol, by matching the result of an expression against a list of known values.

You can use the "_id&" property as a quick way of getting lots of colour into a map. It can be used in conjunction with other themes, e.g. Extrude 2D items in 3D views.
