Backwards-Incompatible Changes

• A major change to the behaviour of the (static and interactive) Mapper plotting functions plot_static_mapper_graph and plot_interactive_mapper_graph was introduced in #584. The new MapperInteractivePlotter class (see "Major Features and Improvements" above) also follows this new API. The main changes are as follows:

  • color_by_columns_dropdown has been eliminated.
  • color_variable has been renamed to color_features (but cannot be an array).
  • An additional keyword argument color_data has been added to more clearly separate the input data to the Mapper pipeline from the data to be used for coloring.
  • node_color_statistic is now applied column by column -- previously it could end up being applied to 2d arrays as a whole.
  • The defaults for color-related arguments lead to index values instead of the mean of the data.

• The default for weight_params in WeightedRipsPersistence is now the empty dictionary, and None is no longer allowed (#595).
