Thanks. The problem is with single precision.
median (diff (xdata) ./ median (xdata))
ans = 1.3607e-08
eps single
ans = 1.1921e-07
You can work around it by ...
xtick = get (gca, "xtick");
xticklabel = get (gca, "xticklabel");
limits = axis () - median (xdata) * [1, 1, 0, 0];
xtick = xtick - median (xdata);
xdata = xdata - median (xdata);
plot (xdata (~isnan (ydata)), ydata (~isnan (ydata)))
set (gca, "xtick", xtick, "xticklabel", xticklabel)
axis (limits)
