Guys, how do you plot multiple rows into a point plot?

Here's what i've done so far:

figure(2)

F = grades(1,:);

E = 1:width(grades);

scatter(E,F)

xlabel('Assignment','FontSize',15);ylabel('Grade','FontSize',15);

yticklabels({'-3','00','02','4','7','10','12'});

title ('Grades per assignment','FontSize',20);

In this code i only plot row 1 but what if i need to plot N Rows? I need to write a code where the input argument is an NxM Matrix.

Whats the content of your variable "grades"?

You can plot multiple lines one after the other with the hold command. (A,B,C,D,E,F are your data vectors)

figure('Name','Example Plot')
scatter(A,B)
hold on
scatter(C,D)
scatter(E,F)
...

You could simply loop over your matrix and plot each line like this.

I did account for that by adding

(1 - 2 * rand) * 0.1

To the data on each cycle. This should be a random number between -.1 and .1. Did this not work?
