Sorting stacked barplot based on abundance values

[nelli-vardazaryan]

Hey,

I am using fantaxtic to create a stacked barplot of relative abundances for each of my samples; however, I am having difficulties controlling the order of each block within each sample. I would like to have these blocks sorted by their abundances in descending or ascending order for easier viewing.

I am using the following code:

top_nested <- nested_top_taxa(ps.rel,
                              top_tax_level = "Phylum",
                              nested_tax_level = "Genus",
                              n_top_taxa = 15, 
                              n_nested_taxa = 15)

plot_nested_bar(ps_obj = top_nested$ps_obj,
                top_level = "Phylum",
                nested_level = "Genus")

Is there a way to change this default behavior?

Hello, Thanks for using fantaxtic! It is possible to sort by samples by abundance, please see the example in the documentation here https://github.com/gmteunisse/fantaxtic?tab=readme-ov-file#sample-order. Sorting taxa by abundance is also possible, but it requires that you build the plot from scratch and relevel the taxa with your desired order; please see the documentation here, specifically the move_label and move_nested_label functions: https://github.com/gmteunisse/fantaxtic?tab=readme-ov-file#advanced-usage Let me know if that is what you’re looking for.
