Using a text file to title a plot.

I have a program that uses many different data sets to generate plots. In order to keep track of where each plot comes from I would like to pull the data set name out of an associated readme file. The trouble is that I can't seem to figure out how to insert the string I get from the readme. My code gets the string with a simple: label = textread(readme.txt, '%s'), but after getting the label I have not figured out how to successfully insert that label into my plot's title (printing label to the screen shows the desired output). Any suggestions?

Thanks to Rick, as this works fine for a single line title. However, I had not noticed that it will not work for me as I am trying to create a two line title. One with the data set name and one with the name of the plot. I have tried using title({label,'x vs t'}) and ({label;'x vs t'}), but only get errors. Any thoughts on why these don't work?

Try
title([label char(10) 'x vs y']) % char(10) for newline

Also,
label ='random title'
title({label,'x vs y'})
should also work. Can you ensure that label is not a cell in your case

I cannot ensure that label is not a cell in this case, which is where I believe the problem was arising. However, the char(10) works perfectly. Thanks Chirag.

The title function should work. For example:
figure;
plot(rand(50,1));
label = 'Some Random Numbers';
title(label);
HTH.

you can also use like this: header{1} ='label'; header{2} ='x vs y'; title ( header)
