I want to make a plot with the time for 41665 values only. How do I achieve this?
figure('position',[50 100 1400 400])
pcolor(datenum(time),rng,zh)
datetick('x')
shading flat

Ran in:
Z = peaks(30) ;
x = datetime(2022,01,01):datetime(2022,01,30) ; % datetime class
y = 1:30 ;
pcolor(x,y,Z)
shading flat

The time variable (x-axis) should be 41665x1; The rng is the Y-axis 600 x1(double); zh has no dimension as its a 2D plot, see attached figure. In the attachment, The vertical space on the RHS with an extra hour (00:00 to 01:00) is to be eliminated from time.
