Follow-up Comment #2:

This is a duplicate of bug #32980.  The issue is that the OpenGL backend
represents values using single precision variables.  The different in time
values you have are less than machine precision for singles (eps ('single')).

The straightforward workaround for now is to re-scale your time values in to
something representable with single precision values.  See the following.


load axisTightData.mat
t_scaled = t / max (t(:));
plot (t_scaled, vout);
axis tight
labels = {"0", "2e-9", "4e-9", "6e-9", "8e-9", "1e-8"};
set (gca, 'xticklabel', labels)


This will get fixed at some point, but it is a deep change to Octave's code
base to workaround the behavior of the OpenGL API.
