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

Comienza ejecutando el ejemplo suministrado de R plot_ly e inspecciona la configuración de xaxis de layout, especialmente categoryorder, tickvals y ticktext. Compara el orden alfabético de las etiquetas con mayúsculas y minúsculas mezcladas y verifica que la leyenda, las categorías del eje x y las barras de error usen el mismo orden. Se considera terminado cuando las etiquetas con mayúsculas y minúsculas mezcladas están ordenadas alfabéticamente sin que las barras de error queden desalineadas.
