Add lines along the axes

I need to add lines along the x and y axes, but I don't want to move the entire axis to the origin. (essentially gridlines, but only at x=0 and y=0) Is this doable easily?

I am not certain what you want.

Try this:

x = linspace(-2, 5, 250);
y = sin(2*pi*x + 0.2) + 0.3;

figure
plot(x, y)
hold on
plot([0 0], ylim, '--')                 % Dashed Vertical Line at x=0
plot(xlim, [0 0], '--')                 % Dashed Horizontal Line at y=0
hold off
grid

If you're using release R2018b or later, you can use the xline and yline functions.
