how to plot graph from text data as shown in the image

Answer 1

[KALYAN ACHARJYA]

Try this way in MATLAB edit window

%Load the file 
A=readmatrix('file.txt');

Get the x and y values

x=A(:,1);
x=A(:,2);

Plot the x and y data

plot(x,y);

Before plotting make sure the lengths of x and y are the same length, if not the same length, then check the data arrangement format within the text file.
