org.dianahep.histogrammar

Categorize

object Categorize extends Factory

Split a given quantity by its categorical value and fill only one category per datum.

A bar chart may be thought of as a histogram with string-valued (categorical) bins, so this is the equivalent of org.dianahep.histogrammar.Bin for bar charts. The order of the strings is deferred to the visualization stage.

Unlike org.dianahep.histogrammar.SparselyBin, this aggregator has the potential to use unlimited memory. A large number of distinct categories can generate many unwanted bins.

Factory produces mutable org.dianahep.histogrammar.Categorizing and immutable org.dianahep.histogrammar.Categorized objects.

    quantity

    Numerical function to split into bins.

    value

    New value (note the =>: expression is reevaluated every time a new value is needed).

    Create an immutable org.dianahep.histogrammar.Categorized from arguments (instead of JSON).

    entries

    Weighted number of entries (sum of all observed weights).

    contentType

    Name of the intended content; used as a placeholder in cases with zero bins (due to no observed data).

    bins

    String category and the associated container of values associated with it.

    Reconstructs a container of known type from JSON. General users should call the Factory object's fromJson, which uses header data to identify the container type. (This is called by fromJson.)
