Hi, try this
filename = 'student_mat.csv' % open file (make sure it exist in the current folder)
T = readtable(filename); % read file as table
age = T.age; % read age column
study_time = T.studytime; % read studytime column
area(age, study_time) % plot them
xlabel('Age')
ylabel('Study Time')
title('Age vs Study time plot')
I used area, You can use any types of plot as you want. Look at this amazing page you can choose what you want.
