Research direction
Start by running the single-observation R example with plot_ly() and the xaxis type and tickformat options, then compare it with the stacked-bar and unformatted examples. Trace how the date axis and tick formatting are handled; done means the single-date bar plot shows the expected tick without introducing extra formatted ticks, while the existing stacked behavior remains unchanged.

Description
In plotly 4.10.4 a bar plot with only one date observation shows actually multiple ticks when the ticks' format is converted. Here a minimal reproducible example:
library(dplyr)
library(plotly)
df <- tibble(Time = "2025-01", Animal = "Monkey", value = 2)
df %>%
plot_ly(x = ~Time, y= ~value, color = ~Animal) %>%
layout(
xaxis = list(
type = "date",
tickformat = "%b '%y"
)
)
This is not the case though for a stacked bar plot:
df <- tibble(Time = c("2025-01", "2025-01"), Animal = c("Monkey", "Lion"), value = c(2, 3))
df %>%
plot_ly(x = ~Time, y= ~value, color = ~Animal) %>%
layout(
barmode = "stacked",
xaxis = list(
type = "date",
tickformat = "%b '%y"
)
)
When looking at the dates without formatting one can see a few minimal shifts around the actual date:
df <- tibble(Time = "2025-01", Animal = "Monkey", value = 2)
df %>%
plot_ly(x = ~Time, y= ~value, color = ~Animal) %>%
layout(
xaxis = list(
type = "date"
)
)
