Plot doesn't fit in graph?

Hey all, I’m a student learning Octave in a Matlab cource so my professor is of no help to me here.

Any plot I build the axis’ stick out of the rectangular area and if I shift the line around to fit within the box, the axis cuts off the line.
How can I get my plots to not truncate/cut off my data, and how do I get them to fit within the box?

Running on Ubuntu 20.04 and on 6.1.0 Octave

Can you post the code you used? I suspect it is simple, but I want to make sure.
