Plotting professional MATLAB graph of given two txt files

Hello,

I'm having to two txt files lets say:

out1.txt

out2.txt

out1 txt has only integer values like this (as column):

100

200

300

400

out2 txt has only integer values like this(as column):

17

18

19

20

I want to plot a good graph (2-D professional graph) of value out1 txt (x axis) versus out2 txt (x axis), x axis called "time" , y axis called "value".

the line of the graph lets say it's a red line / graph.

Any idea how I can do that in matlab a function that gets as input two txt files and plot the graph of their value as I described above?

Much appreciated !

x = load('out1.txt');
y = load('out2.txt');

figure();
plot(x,y);
xlabel('time');
ylabel('value');

but that don't plot the line / graph as red color , am I wrong?

To get a red line:

plot(x,y,'r');

Try this

% Read in data
x = readmatrix('out1.txt');
y = readmatrix('out2.txt');
% Plot it.
plot(x, y, 'r-', 'LineWidth', 3); % Thick red line.  Adjust as desired.
% plot(x, y, 'r.-', 'LineWidth', 3, 'MarkerSize', 25); % Alternative, if you want dots for markers.
xlabel('Time', 'FontSize', 20); % Adjust font size as desired.
ylabel('Value', 'FontSize', 20);
title('Here is my good graph', 'FontSize', 20);
grid on;
% Maximize figure
g = gcf;
g.WindowState = 'maximized'

See attached demo if you want to change anything else, like axes colors, tick marks colors/sizes/colors, etc.
