class lux.processor.Compiler.Compiler

Given a intent with underspecified inputs, compile the intent into fully specified visualizations for visualization.

__init__()

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__()	Initialize self.
compile_intent(ldf, _inferred_intent)	Compiles input specifications in the intent of the ldf into a collection of lux.vis objects for visualization.
compile_vis(ldf, vis)
determine_encoding(ldf, vis)	Populates Vis with the appropriate mark type and channel information based on ShowMe logic Currently support up to 3 dimensions or measures
enforce_specified_channel(vis, auto_channel)	Enforces that the channels specified in the Vis by users overrides the showMe autoChannels.
enumerate_collection(_inferred_intent, ldf)	Given specifications that have been expanded thorught populateOptions, recursively iterate over the resulting list combinations to generate a vis list.
populate_data_type_model(ldf, vis_collection)	Given a underspecified Clause, populate the data_type and data_model information accordingly
populate_wildcard_options(_inferred_intent, ldf)	Given wildcards and constraints in the LuxDataFrame’s intent, return the list of available values that satisfies the data_type or data_model constraints.
remove_all_invalid(vis_collection)	Given an expanded vis list, remove all visualizations that are invalid.
