Plotting time-series data

I have an excel file from which I read the inputs corresponding to different months and years (from Jan,1901 to Dec, 2014). I used that input to get my output for these points in time.

The output i get is stored in the matrix named "PET". I have to plot these PET values on y-axis and the time stamps to which they belong on the x-axis.

I am attaching here the output matrix. (The first row are numbers for Jan 1901, second row for Feb 1901 and so on until Dec, 2014....The columns represent different places for which the input was given and output was to be calculated. Here I need to plot any one of the columns, say col 1, against the time stamps). Please offer me any help.

Regards,

Piyush

Piyush - do you already have a 1368x1 column of timestamp data?

Yes. If you consider one of the columns, it has 1368 data (each corresponding to different time stamps). I do not know how to associate time stamps with these data values and get a timeseries plot.

ts = datetime([1901, 1, 1]) + calmonths(0:size(PET,1)-1).';

plot(ts, PET(:,3))   %for example

Thank you so much, Sir. That works really as required.
