How can I merge three plots into one plot?

Hello all

I have three separated graphs obtained from three separated m.files and I need to merge them into one single graph in order to comapre them to each other. How can I do that?

Thanks in advance

HI @Mir Sahand

To merge three separate graphs into one single graph for comparison, you can follow below steps:

1. Load your data

2. Use the "hold on" command to overlay multiple plots on the same graph

https://www.mathworks.com/help/matlab/ref/hold.html

Here's an example:

% Load data from the first file
data1 = load('file1.m');
x1 = data1.x;
y1 = data1.y;
% Load data from the second file
data2 = load('file2.m');
x2 = data2.x;
y2 = data2.y;
% Load data from the third file
data3 = load('file3.m');
x3 = data3.x;
y3 = data3.y;

% Plot the first graph
figure;
plot(x1, y1, 'DisplayName', 'Graph 1');
hold on; % This keeps the current plot so that new plots are added to it

% Plot the second graph
plot(x2, y2, 'DisplayName', 'Graph 2');

% Plot the third graph
plot(x3, y3, 'DisplayName', 'Graph 3');

xlabel('X-axis Label');
ylabel('Y-axis Label');
title('Combined Graph');
legend show; 

Hope this helps
