Details:

The axis properties xaxislocation and yaxislocation documented here:
https://octave.org/doc/v4.0.1/Axes-Properties.html list the possible options
as:

xaxislocation: {"bottom"} | "top" | "zero"
yaxislocation: {"left"} | "right" | "zero"

The following code sets the xaxislocation to "zero"


figure
plot([0 1],[0 0])
axis([-1 1 -1 1])
grid on
ax = gca;
set(ax, "xaxislocation", "zero");


It produces the error:
error: invalid value = zero

Running the above code with the value "origin" used instead of "zero" produces
the desired result. The correct options for xaxislocation should be:

xaxislocation: {"bottom"} | "top" | "origin"
yaxislocation: {"left"} | "right" | "origin"
