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

まず、提供された R plot_ly の例を実行し、layout の xaxis 設定、特に categoryorder、tickvals、ticktext を確認します。大文字と小文字が混在するラベルのアルファベット順を比較し、凡例、x 軸のカテゴリ、エラーバーが同じ順序を使用していることを検証します。大文字と小文字が混在するラベルがアルファベット順に並び、エラーバーの対応がずれていなければ完了です。
