bar not more working

Hello, I have

Classification_Values =

           0
        3001
        4102
x = 

  1×3 categorical array

     TP      FN      FP 
     

and I get error:

291 Classification_Values = [TP_save; FN_save; FP_save];

Error using bar (line 216)

Data inputs must match the axis configuration. A numeric axis must have numeric data inputs or data inputs which can be converted to

double.

Error in Analysis_algorithm_26_06_20 (line 292)

b = bar(x, Classification_Values);

do you see something wrong? Thanks

disp('Bar plot')
tic
hold on
shortname = extractBefore(name, "_m");
title_help = ["Analysis_Bar:_Messsetup:_" + shortname + "_SNR:_",num2str(SNR_name)];
title_help = join(title_help);
title_help = strrep(title_help," ","");
title(title_help,'Interpreter','none');
x = categorical({'TP','FN','FP'});
x = reordercats(x,{'TP','FN','FP'});
Classification_Values = [TP_save; FN_save; FP_save];
b = bar(x, Classification_Values);
b.FaceColor = [0.6350 0.0780 0.1840];
%title("Result: " + mat_file_name,'Interpreter','none')
ylabel('Value')
toc
disp(['[' 8 cuts ']' 8]);

Remove x from bar(...) and use it as xticklabels(...).
