#initialize(data_series, meta_data, options) ⇒ ScaledDatasetOutput

method to print a given dataset scaled by the terminal size

Parameters:

  • data_series (DataSeries) —

    the data series from which the dataset at the provided index should be visualized

  • meta_data (VisMetaData) —

    the corresponding meta data

  • options (Hash) —

    hash with the relevant parameter values
