03/16/2023, 6:36 PM Copy code
Plot.plot({
marks: [
Plot.barX(fruitData, Plot.groupZ({x: "sum"}, {
x: "value",
fill: "fruit",
order: "x",
// reverse: true // this doesn't seem to change things
}))
]
})Aaron Dennis
03/16/2023, 6:36 PMI can't explain why it works

03/16/2023, 6:38 PMHmm, that still doesn’t seem to be working for me. That order flip reverses for you?

Aaron Dennis
03/16/2023, 6:38 PMthe reverse doesn't work
Aaron Dennis
03/16/2023, 6:39 PMi just swapped the direction of the stacking

03/16/2023, 7:53 PM@Fil - Any insights about using
reversef
Fil
03/16/2023, 8:39 PMreverse is applied before grouping, so the groups are made in the reverse order (which is a useless operation)
Fil
03/16/2023, 8:40 PMIn this case you want to be explicit that it's the stacking operation that needs order+reverse:
Copy code
Plot.plot({
marks: [
Plot.barX(
fruitData,
Plot.stackX(
{
order: "x",
reverse: true
},
Plot.groupZ(
{ x: "sum" },
{
x: "value",
fill: "fruit"
}
)
)
)
]
})🙌🏻 1

03/16/2023, 8:42 PM... so to 'reverse' the original, one changes to 'false'
f
Fil
03/16/2023, 8:44 PMno: the order in the original was just not working (since "z" doesn't exist on this dataset)

03/16/2023, 9:45 PMAppreciate the help! I find myself doing this a bunch and helpful to see the stack and group transforms separated out.

03/16/2023, 11:32 PMSimmering on this, realizing the order in which some of the transformations/groups/etc. are performed seems like a flow I’d like to better understand. Are there any resources for how a Plot chart is rendered as in some of these kinds of orders-of-operation?
• I’m reminded of the order a sql query is performed, helpful in constructing a query for desired results.
Thanks!
