steenroder.plot_diagrams

steenroder.plot_diagrams(barcode, steenrod_barcode, k=None, kind=None, tex=False, plotly_params=None)[source]

Plot a regular persistence barcode and a Steenrod barcode as diagrams on a common birth-death plane.

Parameters

  • barcode (list of ndarray) – The persistence barcode to plot. For each dimension d, a 2D array with 2 columns, containing birth-death pairs in degree d, to be used as coordinates in the two-dimensional plot.

  • steenrod_barcode (list of ndarray) – The (relative) Sq^k-barcode to plot. For each dimension d, a 2D array with 2 columns, containing the birth-death pairs of Steenrod bars in degree d, to be used as coordinates in the two-dimensional plot.

  • k (int or None, optional, default: None) – Positive integer defining the cohomology operation Sq^k that was performed to obtain steenrod_barcode. Only used for labelling.

  • kind ("R" | "A" or None, optional, default: None) – Whether the barcodes to be plotted come from absolute or relative cohomology barcodes.

  • tex (bool, optional, default: False) – (Experimental!) Whether to display a version of the legend rendered with LaTeX and MathJax.

  • plotly_params (dict or None, optional, default: None) – Custom parameters to configure the plotly figure. Allowed keys are "traces" and "layout", and the corresponding values should be dictionaries containing keyword arguments as would be fed to the update_traces and update_layout methods of plotly.graph_objects.Figure.

Returns

fig – Figure representing the persistence diagram and Steenrod diagram.

Return type
