MATLAB: plotting data from struct

问题

I have a structure of data that contains data values, time, unit, and some descriptions of each data. I want to plot the data values vs time. Here is how the data looks like:

Any ideas how i can plot the data and time?

Quick example:

%# date strings and values
dates = {'02.11.2012 00:02:15'; '02.11.2012 00:07:12'};
values = [5.8; 5.7];

%# convert to serial date numbers
t = datenum(dates, 'mm.dd.yyyy HH:MM:SS');

%# plot and format x-ticks as datetime
plot(t,values)
datetick('x')

You Need not open the entire readings and then plot the Graphs of those. Instead you can directly Access the strucure and plot the graph by this command :

• plot(data.(data.arrayOfTimestamp),data.arrayOfValue)
