Hi,
when I'm plotting data as bar plot with a serial day number on the x-axis
either the y-axis is not nice and the data is squeezed (Figure 1) or the
x-axis does not show the correct time but only 00:00 (see Figure 2). Is there
a way to avoid these incidents?


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]';

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

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