Is it possible to create textbox with fixed width on a plot?

I would like to add paragraph with fixed width as a caption to the figure, but I don't want to set by hand the linebreaks!

You can use the annotation textbox with the 'FitBoxToText' property set to 'off'. This will wrap the text to fit the width of the text box.

Ex:

>>figure; % new figure window
>>plot(1:10);
>>annotation('textbox', [0.2,0.4,0.5,0.1],...
'String', 'This is a test string.This is a test string.This is a test string.This is a test string.',...
'FitBoxToText','off');

You can refer to other properties here:

The 4 position parameters seem to relative to the entire figure rather than an pair of axes in a subplot. Can this be done within a subplot?

AFTERNOTE: With help from [https://www.mathworks.com/matlabcentral/answers/356708-how-to-position-a-annotation-in-subplot-southeast], I supplied "get(gca,'Position')" as the "dim" name/value parameter:

annotation('textbox',get(gca,'Position'),String="The quick brown fox",FitBoxToText='off')

Unfortunately, the text box's left edge overlaps with the y-axis labels!

A work-around that doesn't involve manual customization of the "Position" based on Figure size and number of subplots would be welcome. Thanks!

P.S. I currently finagle the position by manually resizing the text box, issuing "get(gco,'Position'), then editing the "annotation" command to use this position. Ideally this would not be necessary.
