I have some plots that I want to write a text on them but I want to place the text in a white space inside plot. I wonder how I can do that?
plot(x,y,'o'); % I want to show the following text in a white space inside the plot window

What you are asking for isn't easy to implement but can be done, what the code has to do is the search for one empty space big enough for that text, there's also a chance that there's no such space available and the code will fail.
There are alternatives like using the legend, xlabel, ylabel and title. Also title can have many lines
title({'Main Title text'; 'Subtitle text'});
or this solution:
title(['\fontsize{14} Main Title ', ...
'\newline \fontsize{10} \color{red} \it My Subtitle']);
There is also the gtext function that allows the user to select where to put the text.

Sorry Paulo for misspelling your name. Well, I just wondered someone may have it done it before since especially for me who is not good in programming it will take ages.

Look in the code of LEGEND, subfunction lscan. This function has 92 lines, because the task is not trivial. But when the found location is nice for a legend, a text may be matching also.
