MATLAB: Plot data with time

dataplottime

I'm trying to plot my data with time on the x-axis. My data has the following csv format:
13:05:48  1.33  5.15
13:05:53  2  5.2
13:05:58  2.1  4.88
There are 3 columns with column 1 being my time(HH:MM:SS) and column 2 and 3 being my data. How do I read then plot Column 1 time vs. my column 2 or 3?

Best Answer

[d,x,y]=textread('ivan.csv','%8s %f %f','delimiter',' ');
dn=datenum(d,'HH:MM:SS');  % ERRATUM: had lowercase in time format string
plot(dn,[x y])
datetick('x')
Alternatively, use textscan or with the latest releases there's a new datetime object
