Constructor Details

#initialize(data_set, meta_data, indices, options) ⇒ ScaledDeltaOutput

method to visualize the difference of two datasets

Parameters:

  • data_set (DataSet) —

    the dataset which should be visualized

  • meta_data (VisMetaData) —

    the corresponding meta data

  • indices (Hash) —

    the indices of the two datasets which should be substracted

  • options (Hash) —

    hash with the boolean values for extreme values and extended legend output
