Query about axes of graph created by plot function

If I have two variables A = [1 2 3] and B = [1 2 3], when I plot(A,B) I get a graph with 10 variables on both x and y axis with constant intervals between 1 and 3.

Is there a way where I can just get a graph with 3 values 1, 2 and 3 on both x and y axis?

I am not certain what the original problem is with your plot.

Try this:

A = [1 2 3];
B = [1 2 3];

figure
plot(A, B)
Ax = gca;
Ax.XTick = A;
Ax.YTick = B;

.

That solved the problem, thank you!

My pleasure!

I suspect that you want to use xlim() and ylim()

[Erika Yoshikawa]

Thank you for your answer. I think xlim() and ylim() limits the values on x and y axis, however it is not what I'm looking for.

When I enter the following:

A = [1 2 3]
B = [1 2 3]
plot(A,B)

I'm getting a graph which is shown in the screenshot:

I don't understand why matlab is changing the interval so there's 10 values on the x and y axes, but I just want 1, 2 and 3 on both x and y axis.

MATLAB automatically chooses "nice" ticks. You can use xticks() and yticks() to choose different tick locations.
