Capital Letters affect alphabetical ordering causing wrong order of legend and x axis

legend order and x axis of bar graph is not fully ordered alphabetically, capital letters take priority causing miss aligned error bars due to different order.

only way to solve my issue was making everything lower case for example PPARy1 was being listed before Perilipin but once lower case it was correct order.

chemical_ct <- SharedData$new(CTdf)

# Step 2-4: Loop through each unique gene, subset data, and create shared objects
filter_checkbox("chl", "chemical", chemical_ct, ~chemicalgroup, inline = TRUE)
if(analysistype=="western"){
  filter_checkbox("prn", "protein", chemical_ct, ~protein, inline = TRUE)
}else{ 
  filter_checkbox("gene", "gene", chemical_ct, ~gene, inline = TRUE)
}

# Specify a set of main colors
main_colors <- c("red", "blue", "green", "yellow", "orange", "purple", "cyan", "magenta", "brown", "gray")

plot <-plot_ly(
  data = chemical_ct,
   error_y = ~list(
    type = 'data', 
    array = CTdf$SEM,
    color = "black"
  ),
  x = ~chemical,
  y = ~average_RQ,
  type = 'bar',
  color = ~graphing_sort,
  colors = main_colors,
  name = ~chemical, 
  
  texttemplate = ~Letters,
  textposition = "outside",
  textfont = list(color = "black",
                  size = 30),
  outsidetextfont = list(color="black")
 
) %>%
  layout(
    xaxis = list(title = "Chemical Concentration",
                 tickmode = 'array',  # Set tick mode to 'array'
                  tickvals = ~chemical,  # Set tick values to be the same as x 
                    ticktext = ~chemical,
                 tickangle = 90,
                 categoryorder = "category ascending"),
    yaxis = list(title = "Fold Change"),
    bargap = 0.1,
    width = 800, 
    height = 800
  ) 
plot

Commencez par exécuter l’exemple R plot_ly fourni et examinez les paramètres xaxis de layout, en particulier categoryorder, tickvals et ticktext. Comparez le tri alphabétique des libellés avec une casse mixte et vérifiez que la légende, les catégories de l’axe x et les barres d’erreur utilisent le même ordre. C’est terminé lorsque les libellés avec une casse mixte sont triés alphabétiquement sans désalignement des barres d’erreur.
