Penguins example looks funny

[jhofman]

Here's another one that looks strange, the bars are misaligned, there are missing grid panels, and the points go beyond the y-axis range

library(datamations)
library(palmerpenguins)

penguins <- palmerpenguins::penguins

"penguins %>%
  group_by(species, island, sex) %>%
  summarize(mean = mean(bill_length_mm, na.rm = TRUE))" %>%
  datamation_sanddance()

Any idea what's up and how to fix this?

(this was run after a fresh devtools::install_github("microsoft/datamations") of datamations this morning)

[jhofman]

this might have to do with facet sorting in the spec?

[giorgi-ghviniashvili]

@willdebras can you remove facet.column.sort and facet.row.sort array on R side? That causes the issue.

Removing these sort calls fixes this. It looks like it doesn't introduce issues in other places, so I am going to just commit this to main.

[giorgi-ghviniashvili]

@willdebras that's great. Could you please also make sure that the y axis titles are not bigger than the facet height? Instead of mean(bill_length_mm), use ["mean", "bill_length_mm"] and it will be fully fixed.

[willdebras]

Yep :) It's like this in main now after merge from yesterday, returning ["mean of", "variablename"]. Just hadn't pulled those changes yet.

[jhofman]

almost there---sorting of the rows changes part way through, see here:

Might need to revert this, as it keeps the sorting consistent with group_by and mutate frames 1ac1cf5

[giorgi-ghviniashvili]

@willdebras alright, right now, I brought back the sorting and trying to fix the other way around.

[giorgi-ghviniashvili]

@jhofman @willdebras I found out that vega-lite facet sort does not work at all and that's why it has this issues.

The issue: vega/vega-lite#5937

The image:

So I guess it is better to remove sorting, unless we hack that too :D

Play with this vega example

[willdebras]

What's your recommendation as far as specs, @giorgi-ghviniashvili? Should I remove all sorting? Removing the facet sorting from summarize spec generation de-syncs it from the group_by(). It seems if we sort all, we get the weird grid. If we unsort in this step, we get the weird shifts from the group_by().
