A cdf property is used to configure a classification scheme for a values unit or data item.


unit<float32> meter := baseunit('m', float32)
,   cdf   = "Classifications/m_4K/ClassBreaks";

cdf properties can be configured to both values units and data items:

  1. If configured to a values unit, all data items with this values unit will use the classification (by default) in map and graph views.
  2. If a cdf property is configured to a data item, it is used in a graph or map view of this data item and overrules a cdf property configured to the values unit of the data item.

The cdf property always needs to refer to the ClassBreaks item of a Classification scheme.
