I have a matrix with 5 columns and I want to plot the fifth one. I also want MATLAB to use dots for the graph and to label the x and y axis. I use plot(matrixname(:,5)) but can't get the graph have dots. Any help is appreciated.

Try this:

plot(matrixname(:,5), '.')

Hello! Thank you for the quick feedback but with your code, I lost my graph. I attach the plots I had with two different codes. plot(dat(:,5)) this is what I tried. plot(dat(:,5), '.') How can I also label the axes with x and y?- Just figured labelling.

My pleasure.

You didn’t lose your graph — the dots are plotted at ±1. If you want lines and dots, and see them easily, do this:

figure(1)
plot(matrixname(:,5), '-.')
axis([xlim    -1.5  1.5])

oh sure! Now I see. Thank you again! :)
