Create stacked volcano plots for comparing differential expression across multiple datasets.

Parameters:

  • data_dict (Dictionary with DataFrames containing 'logfoldchanges', 'pvals_adj', 'names' columns.)

  • color_dict (Dictionary mapping dataset names to colors)

  • pval_threshold (P-value significance threshold (0.01))

  • log2fc_threshold (Log2 fold change threshold (2))

  • figsize (Figure size ((8,4)))

  • sig_color (Color for significant points ('#a51616'))

  • normal_color (Color for non-significant points ('#c7c7c7'))

  • plot_genes_num (Number of top genes to label (10))

  • plot_genes_fontsize (Font size for gene labels (8))

  • plot_genes_weight (Font weight for gene labels ('bold'))

Return type:

tuple

Returns:

Tuple of (figure, axes_dict)
