R plotly boxplots overwriting with numerical labels

R plotly boxplots overwriting with numerical labels

I've asked this question on SO here: https://stackoverflow.com/questions/76466189/r-plotly-boxplots-overwriting-with-numerical-labels, but I'm wondering if it's a bug with the latest versions of the plotly library in R

Plotting boxplots with numeric (or numeric-as-character) as x-variable results in boxplots a) not located in the correct locations and b) with boxes overplotted

library(plotly)

colors <- c("red","blue","green","pink","brown")
data.in <- data.frame(Age=25*rnorm(100)+50, IMD=sample(5,100,replace=TRUE))
fig <- plot_ly(data=data.in[data.in$IMD == "1",], y=~Age, type="box", color=I(colors[1]),name="1 - least")
fig <- fig %>% add_trace(data=data.in[data.in$IMD == "2",], y=~Age, type="box", color=I(colors[2]),name="2")
fig <- fig %>% add_trace(data=data.in[data.in$IMD == "3",], y=~Age, type="box", color=I(colors[3]),name="3")
fig <- fig %>% add_trace(data=data.in[data.in$IMD == "4",], y=~Age, type="box", color=I(colors[4]),name="4")
fig <- fig %>% add_trace(data=data.in[data.in$IMD == "5",], y=~Age, type="box", color=I(colors[5]),name="5 - most")
fig <- fig %>% layout(yaxis = list(title = "Age"),
                      xaxis = list(title = "IMD"),
                      boxgap = 0.1, boxgroupgap=0)

This results in a plot similar to

Specifying 'x=~' in each add_trace does place the boxes in the correct places so is a temporary workaround, but I think that this may be a bug with the package, as the above code with labels which don't start with numbers (in the 'name=' attribute) does give the correct placement:

library(plotly)

colors <- c("red","blue","green","pink","brown")
data.in <- data.frame(Age=25*rnorm(100)+50, IMD=sample(5,100,replace=TRUE))
fig <- plot_ly(data=data.in[data.in$IMD == "1",], y=~Age, type="box", color=I(colors[1]),name="A")
fig <- fig %>% add_trace(data=data.in[data.in$IMD == "2",], y=~Age, type="box", color=I(colors[2]),name="B")
fig <- fig %>% add_trace(data=data.in[data.in$IMD == "3",], y=~Age, type="box", color=I(colors[3]),name="C")
fig <- fig %>% add_trace(data=data.in[data.in$IMD == "4",], y=~Age, type="box", color=I(colors[4]),name="D")
fig <- fig %>% add_trace(data=data.in[data.in$IMD == "5",], y=~Age, type="box", color=I(colors[5]),name="E")
fig <- fig %>% layout(yaxis = list(title = "Age"),
                      xaxis = list(title = "IMD"),
                      boxgap = 0.1, boxgroupgap=0)

从提供的 R 复现开始，使用 plot_ly()、add_trace() 和 layout()；比较数值型和非数值型 trace 名称，以及显式 x= workaround。完成的标准是：数值型或以字符表示的数值型 boxplot trace 占据不同且预期的 x 位置，而不需要显式的 x 值。issue 中未指定源文件或测试。
