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

首先运行提供的 R plot_ly 示例，并检查 layout 的 xaxis 设置，尤其是 categoryorder、tickvals 和 ticktext。比较大小写混合标签的字母顺序，并验证图例、x 轴类别和误差条使用相同的顺序。大小写混合标签按字母顺序排列且误差条没有错位，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,

                 tickmode = 'array',  # Set tick mode to 'array'
                  tickvals = ~chemical,  # Set tick values to be the same as x 
                    ticktext = ~chemical,
                 tickangle = 90,
