issues with plots with multiple information

I need to plot those information but it's show me "Error using plot

Vectors must be the same length."

All the information provided and text file.

clear;
clf('reset');
max_iterations = 1000;
xs = 1: max_iterations;
num_devices=50;
ys_00=importdata('NOMA_users.txt');
ys_01=importdata('NOMA_users.txt');
ys_02=importdata('NOMA_users.txt');
ys_00 =NOMA_users(1:max_iterations, 1);

Unrecognized function or variable 'NOMA_users'.

b = bar(xs, ys_00);
plot(xs, ys_00); 
hold on;
plot(xs, ys_01);
plot(xs, ys_02);
ylim([0 num_devices]);
title({title_text_1; title_text_2; title_text_3})
 xlabel("Iterations");
ylabel("Number of selected clients");
%  legend({'Number of selected clients by LEARN ', ...
%         'LEARN (after energy filtering)', ...
%         'GREED'}, ...
%        'location', 'northwest');
%   set(gca,'XMinorTick','on','YMinorTick','on');
% grid on;
TextFontSize=25;
LegendFontSize = 20;
set(0,'DefaultAxesFontName','Times',...
    'DefaultLineLineWidth',1,...
    'DefaultLineMarkerSize',6);
set(gca,'FontName','Times New Roman','FontSize',TextFontSize);
 hold off;

  clear;
figure;
clf('reset');
plot(xs,ys1, '-bo');
ylim([0 num_devices]);
% title({title_text_1; title_text_2; title_text_3})
ylabel(ylabel_text_1);
xlabel('Mean value of $\mu_{i}$', 'interpreter', 'latex');

Thats because the length are not the same. Send in the data, so I can see how to fix it

[Brave A]

I already attached the text file which has 1000 values.

Any Ideas?

still get this messgae

Index in position 1 exceeds array bounds (must not exceed 599).

ys_00 =NOMA_users(1:max_iterations, 1);

NOMA_users does not exist as a function or variable in your code. You read in data from a file with that name, but you store the data in ys_00

We can speculate that in your real code you are doing

ys_00 = ys_00(xs, 1);

Later you plot xs vs ys_00 and that should work because they are the same length.

ys_01=importdata('NOMA_users.txt');
ys_02=importdata('NOMA_users.txt');

That is the same input file name as what you already read in.

Later you plot xs vs ys_01 but unlike with ys_00 you did not extract a subset of the file, so your x is length 1000 but your ys_01 is the full file of data. You probably need

ys_01 = ys_01(xs, 2);

or something similar, and likewise for ys_02

Here is the data for ys_00, I attached them. Sorry still the code not working :(

Error in Noma_compare (line 50)

ys_00 = ys_00(xs, 1);

use

ys_00 = importdata('NOMA_users.txt');
max_iterations = min(1000, size(ys_00,1));
xs = 1:max_iterations;
ys_00 = ys_00(xs, 1);
