Starting in MATLAB R2023b, you can add, remove, or update the secondary labels using
xsecondarylabel, ysecondarylabel, zsecondarylabel
Demo
plot(datetime(2014,6,9)+days(0:9), 0:9)
xsecondarylabel(Visible="off")

It is good news to me but I am still stuck on 2021b version.
Thank you for caring about this even after 3 years.

I realize @Euigyeong Hong is stuck on R2021b, but for others who come across this answer:
Starting in R2024a you have even more control over the secondary label.
  • You can use the xsecondarylabel command (introduced in R2023b) to hide the label (set Visible='off') or set a manual string to hard-code your secondary label.
  • Starting in R2024a, you can now set the SecondaryLabelFormat property on the x-axis if you want to change the formatting of the label without losing the automatic nature.
ax = axes;
plot(ax, datetime(2014,6,9)+days(0:9), 0:9);
ax.XAxis.SecondaryLabelFormat = 'yyyy-MM';

You can do it by running the following statements.
ax = gca;
ax.XTickLabel = ax.XTickLabel;
or
ax = gca;
ax.XTickLabelMode = 'manual';

I think for normal visualization, when you need to zoom on the axes, the date might not be an issue. Just turn it off when printing or saving the image.

If you just want the duration data for the time of day on the x-axis, you can use the timeofday method for datetime.
>> x = datetime('today'):hours(1):datetime('today')+hours(10);
>> y = 0:10;
>> plot(timeofday(x),y)
>> xtickformat('hh:mm')

Thanks, Seth.
But I am finding to see the plot by auto-format mode because when I zoom in to short time it is easy to see "hh:mm:ss.SSS" format by itself. After checking the plot, I copied the figure, but the number of figure was 20~30, so I was unhappy.
