Plot different length vectors on the same x-axis

Hi, I've got the following situation on my hands:

I have three matrixes that contain the number of epochs plus a few metrics for the training of a machine learning algorithm, for a total of 5 columns each.

The first table has 193 rows, the second and third ones have 173.

I would like to plot the second column of each matrix on the same plot, using the first column of the biggest matrix as x axis. My idea would be to obtain a plot in which the first line arrives to the limit of the x axis and the other two stop earlier.

Thank you for your attention.

So you have to do something like

plot(matix1(:,1),matix1(:,2)); hold on;
plot(matix1(1:173,1),matix2(:,2));
plot(matix1(1:173,1),matix3(:,2));

well thank you, that was easier than I'd thought
