Increase width of x axis

I want to increase the width of the x axis of a plot.

Changing set(gcf, 'Position', [100, 100, 650, 650]) just increases the size of the window of the figure, not the plot's width. I do not want to change the height, just the width.

How can I do this?

Thank you in advance!

set(gca,'linewidth',6)

This increases the thickness of the lines, I just want to increase the length of the axis.

I have figured it out, I had to add set(gca,'FontSize',12,'DataAspectRatio',[1 1.75 1]) for it to work.

Thank you for the help.

You need to set gca and not gcf:

set(gca, 'Position', ...)

Hello, thank you for your answer. I tried setting this, but the figure just comes out completely blank. What could be causing this? I assured that the size of the axes was smaller than the size of the figure...
