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

What are dimensions of xtime, rng and zh?

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.
