Sort samples by metadata category

[nerdynella]

Hi @jairideout any updates on this yet? Continuing the discussion from Is there any way to summarize taxa plot by category?:

Hi @m-ocejo! We currently don’t have that functionality in QIIME 2’s taxa barplots. I created an issue to track the addition of that feature. Note that you can sort the samples by a metadata category, so that samples from the same category will be grouped together (but each bar will still represent a single sample).

Also, how do I achieve this?

Hi @nerdynella!

Hi @jairideout any updates on this yet?

Unfortunately, no. We haven't had a chance to work on this, and we don't have a good ETA at present.

@nerdynella

Also, how do I achieve this?

The sort is controlled by the widgets off to the right side of the visualization, under the label "Sort Samples By".

Using the Moving Pictures barplots as an example:

Here we are sorting by k__Bacteria;p__Firmicutes

Here we are sorting by BodySite. Also note the x-axis labels reflect the body site. This is what @jairideout was referring to.

You can chain multiple sort parameters by clicking the blue plus icon. Here we are sorting by BodySite, and then by Subject.

Hope that helps!

@thermokarst this definitely helps! I missed the sort sample tab earlier (for some reason i wrongly assumed that it could only sort by taxonomic level prolly because of the k_bacteria).
Thank you!
