It gives you a high level API to build complex plot is a simple way. This is the Horizon class which lets you build your Horizon charts just passing the arguments to the Chart class and calling the proper functions. i(tabsolute_import(tFloattInttListt string_typestStringtColortBool(tCategoricalAxis(tColumnDataSource(t FactorRanget DataRange1d(tcreate_and_build(t HorizonGlyphi(t LineBuilderi(t ColorAttrtIdAttrcK@s ||d<||d<||d<|jdtƒ}|tkrEd}nZt|tƒrŸ|jddƒ}|jddƒ}|jd dƒ}|jd d ƒ}n||d` to render the geometry from values. Args: data (:ref:`userguide_charts_data_types`): table-like data x (str or list(str), optional): the column label to use for the x dimension y (str or list(str), optional): the column label to use for the y dimension In addition to the parameters specific to this chart, :ref:`userguide_charts_defaults` are also accepted as keyword parameters.
