I would to keep the same order of the categorical array (redbox on the side) along the x-axis on the chart.

stem(categorical(C),D,'Filled','Markersize',10);

Try manually change xticklabel

h = stem(...);
set(h,'xticklabel',[1 2 3])

Unfortunately I have already tried ... it doesn't work!

By default, Categoricals are organized in alphanumeric order. If you want to impose your own order on them, use the reordercats function. Since we don't have your code or files, here's a simple example using the months of the year.

month = ["January","February","March","April","May","June","July","August","September","October","November","December"];
m = categorical(month);
% Show order of categories (alpha-numeric)
categories(m)

ans = 12×1 cell array    
'April'       
'August'      
'December'    
'February'    
'January'     
'July'        
'June'        
'March'       
'May'         
'November'    
'October'      
'September'    

m = reordercats(m,month);
% Show updated order of categories (imposed order)
categories(m)

ans = 12×1 cell array    
'January'      
'February'     
'March'        
'April'        
'May'          
'June'         
'July'         
'August'       
'September'    
'October'      
'November'     
'December'
