[Pantxo Diribarne]

Update of bug #56276 (project octave):

                  Status:                    None => Duplicate              
             Open/Closed:                    Open => Closed

Follow-up Comment #1:

This is due to the OpenGL rendering engine that uses single precision. See bug
#32980.

To workaround this issue, since you plot data that are all enclosed in a
single day, you can remove the day offset:


close all
clear all

data = rand(10,1);
starttime = datenum(2019,5,6,6,0,0);
endtime = datenum(2019,5,6,15,0,0);
xtime = [starttime:1/24:endtime]' - floor (starttime);

figure();
bar(xtime, data);
datetick('x', 'HH:MM')


Closing report as a duplicate.
