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

首先執行提供的 R plot_ly 範例，並檢查 layout 的 xaxis 設定，尤其是 categoryorder、tickvals 和 ticktext。比較大小寫混合標籤的字母順序，並驗證圖例、x 軸類別和誤差線使用相同的順序。大小寫混合標籤依字母順序排列且誤差線沒有錯位，即表示完成。

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,

  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,
