Good. At least you know what you want to do. So plot whatever you want. What is the problem?

[karim Soussou]

I don’t know how to enter all this data to plot the x bar and R

[Voss]

Where is the data now? In a text file? If it is in a file (of any kind), please attach the file here so that people can advise you on the correct way to get the data into your MATLAB workspace.

I have absolutely no idea what and R are.

Two possibilities —

M = [1  44  26  24  34  
2  50  48  51  43 
3  32  28  26  22 
4  52  55  56  44 
5  16  16  21  26 
6  36  36  35  31 
7  21  22  18  21 
8  29  21  23  22 
9  26  46  44  14 
10  24  22  22  44 
11  18  24  24  49 
12  24  20  26  23 
13  19  21  27  28 
14  8  11  12  12 
15  24  18  27  24 
16  56  52  56  50 
17  32  22  18  25 
18  8  12  11  17 
19  51  54  52  49]; 
T1 = array2table(M, 'VariableNames',{'s No','1','2','3','4'})

T1 = 19×5 table
    s No    1     2     3     4 
    ____    __    __    __    __

      1     44    26    24    34
      2     50    48    51    43
      3     32    28    26    22
      4     52    55    56    44
      5     16    16    21    26
      6     36    36    35    31
      7     21    22    18    21
      8     29    21    23    22
      9     26    46    44    14
     10     24    22    22    44
     11     18    24    24    49
     12     24    20    26    23
     13     19    21    27    28
     14      8    11    12    12
     15     24    18    27    24
     16     56    52    56    50

VN = T1.Properties.VariableNames;

figure
plot(T1.('s No'), T1{:,2:5})
grid
hl = legend(VN{2:5}, 'Location','SW');
title(hl, '$\bar{x}$', 'Interpreter','latex')
xlabel('s No')
ylabel('R')

figure
surfc(T1{:,2:5})
yticks(T1{:,1})
xlabel(['$' VN{1} '$'], 'Interpreter','latex')
ylabel('$\bar{x}$', 'Interpreter','latex')
zlabel('$R$', 'Interpreter','latex')

Make apopropriate changes to get the desired result.
