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');

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.
