A matrix visualization of the nullity of the given AnnData object.

  • adata (AnnData) – AnnData object object containing all observations.

  • filter (str | None) – The filter to apply to the matrix. Should be one of “top”, “bottom”, or None. Defaults to None .

  • max_cols (int) – The max number of columns from the AnnData object to include.

  • max_percentage (float) – The max percentage fill of the columns from the AnnData object.

  • sort (str | None) – The row sort order to apply. Can be “ascending”, “descending”, or None.

  • figsize (tuple) – The size of the figure to display.

  • width_ratios (tuple) – The ratio of the width of the matrix to the width of the sparkline.

  • color (tuple) – The color of the filled columns.

  • fontsize (float) – The figure’s font size.

  • labels (bool) – Whether or not to display the column names.

  • label_rotation (float) – What angle to rotate the text labels to.

  • sparkline (bool) – Whether or not to display the sparkline.

  • categoricals (bool) – Whether to include “ehrapycat” columns to the plot.
