Facets

With the facet operator, we can partition a dataset by a field and create a view for each field. The resulting chart is often called a small multiples chart.

Facet Properties

(facet,channel) : The facet channel. Can be one of col and row.

(facet,field) : The facet field. Note that the field should refers to field name rather than the field entity id. Although we specify the name and the id in the same way in the following examples, they can be different.

(facet,binning) : Binning a numeric field for faceting.

Example

entity(field,root,condition).
attribute((field,name),condition,condition).
attribute((field,type),condition,string).

entity(view,root,v).

entity(facet,v,f).
attribute((facet,channel),f,col).
attribute((facet,field),f,condition).

entity(field,root,temperature).
attribute((field,name),temperature,temperature).
attribute((field,type),temperature,number).

entity(view,root,v).

entity(facet,v,f).
attribute((facet,channel),f,col).
attribute((facet,field),f,temperature).
attribute((facet,binning),f,10).
