How to plot timeline in matlab?

Hi, all,

I want to plot a figure with x-axis is timeline, for example, from 9am to 11pm, and every 10 or 15 minutes are one epoch. Does matlab provide some code for a timeline axis? Thanks.

% Create dates as serial numbers
serdates = fix(now) + 9/24 :  1/(24*4) : fix(now) + 11/24;

% plot
plot(serdates,rand(1,9))

% Set ticks to serial dates (just to make sure they fall on serdates)
set(gca,'xtick',serdates)

% Format into time 
datetick('x','keepticks')

Oleg, why fix(now)?

 serdates = 9/24 :  1/(24*4) : 11/24;

is fine

If you wanna plot for multiple days you have to start somewhere, I chose now().
