The axis you want to sort isn't

x

, but

fx

. Try

fx: { domain: order }

. That's "facet x"

the link is in my description

oh, apologies

it's fine, always appreciate anyone's response

ok, yes. setting the domain of

fx

works for me: https://observablehq.com/d/dd878dcd8ebbc322

do you know when I should use

fx

, I think the variable name confuses me

fx

is the channel name for the horizontal facet direction. You'd use that if you want to affect the facets of the chart, and you'd use

x

when you want to affect the horizontal channel within one chart

@Michael Cooper so for a single (not grouped) regular bar chart, there is only one facet?

I'd think about it as not being faceted, but I think only having one facet is correct too

and channel in this case is a list of items that was used for each facet. I was trying to understand the relationship in and out I guess

a channel is the way that Plot talks about how you can visually encode data https://observablehq.com/plot/features/marks#marks-have-channels

Maybe here the terminology is a bit confusing: In general faceting means adding one or more dimensions based on which you "replicate" your main Plot for each category. This notebook is called Grouped bar chart, in Plot you generally use group, like Plot.group(..) for aggregating data based on a categorical attribute

You're right, that notebook has nothing to do

Plot.group

, which is a bit confusing

the

Plot.group

is used for grouping the rawdata before they are used for rendering right?

yeah. it would be more correct to say that the notebook is demonstrating a faceted bar chart, not a grouped one

this is actually one of the official example

I'm one of the official employees 😉. I can pass this along to our docs team

I also suspect that grouped was chosen for familiarity, as mentioned by @tan tan. The best docs aren't worth much if you can't find them 😁

I would recommend reading the new Plot docs. We launched them a few weeks ago, and in my opinion they are an excellent way to learn the library: https://observablehq.com/plot/

It really depends on the reader's background,

group

can be confusing for developer like me cuz there are some common terms used inside the code (mathematically) and outside of the code (daily life) that hold completely different meanings. But maybe it makes sense for general data science people. 😂 idk, just a user feedback I guess
