intentional duplicated catergorical items disappear when plotting

[jblamyatifremer]

Dear plot_ly creators,

I am using R and I am trying to plot a heatmaps with duplicates items (in x and y axis) to ease the visualization. The items are categorical. I also read all issues regarding the categorical axis : #189 #242, #399, #379. But here the problem is different.

I create a simple code to reproduce the problem :

## create fake dataset
m <- matrix(rnorm(9), nrow = 3, ncol = 3)
x <- c("a", "a", "c")
y <- c("d", "e", "e")

## plot it
t <- plot_ly(
    x = x, y = y,
    z = m, type = "heatmap"
)
t

I expected to get a 3 X 3 heatmaps, but I only get a 2 X 2 heatmaps. I also tried my elaborate code :

## use the same dataset as above
ax <- list(
    type = "category",
    categoryarray = x,
    categoryorder = "array",
    showgrid = TRUE,
    showline = TRUE,
    autorange = TRUE,
    showticklabels = TRUE,
    ticks = "outside",
    tickangle = 45,
    tickfont=30
)

ay  <- list(
    type = "category",
    categoryarray = y,
    categoryorder = "array",
    showgrid = TRUE,
    showline = TRUE,
    autorange = TRUE,
    showticklabels = TRUE,
    ticks = "outside",
    tickangle = 0,
    tickfont=30
    
)

t <- plot_ly(
    x = x, y = y ,
    z = m, type = "heatmap"
)  %>%
    layout( margin = list(l = 150, r = 50, b = 150, t = 0, pad = 4), title = 'relatedness R',
            xaxis = ax, yaxis = ay)
t

I got exactly the same results. Any idea to solve/trick this will be welcome.

Dear all,
Solution found. It is rename the duplicated item !

## create fake dataset
m <- matrix(rnorm(9), nrow = 3, ncol = 3)
x <- c("a", "aa", "c")
y <- c("d", "e", "ee")

## plot it
t <- plot_ly(
    x = x, y = y,
    z = m, type = "heatmap"
)
t
