Plotting Data From Constantly Updating Textfile

I would like to plot data from a textfile which has a new entry every 10 seconds (or time period around 10 seconds), and for the plot to update as well.
To do that would I basically have to refresh the plot or rerun the program or is there a way to keep on reading a textfile whose length is always changing, and to add more data points to a plot to reflect the new data in the text file?
Thank you very much

You can get the time stamp of file if file gets modified....using:
FileInfo = dir('my text file') ;
TimeStamp = FileInfo.date;
% Get individual components of date & time in 1 Sec resolution
[Y, M, D, H, MN, S] = datevec(FileInfo.datenum);
When ever there is change in the time stamp, you read the file and plot/ update the plot. YOu can put the code in while loop.
