Plot title divided into rows, why?!

I have attached my code below.

When I run this code, the title to my plots look like this (see attached picture). Why is this? In the code, the array "M_G_gsm" is just an array of strings. This was not previously used to make the title, then I just wrote the title by hand. I believe this problem has to do with the string array, but I cant figure out how. Can anyone suggest a solution? I just want the title to become a row, like normal.

Thank you in advance

Henry

It is probably because your concatenation is having unforeseen effects.

Try this instead:

title(sprintf('E%d %s %s %s all packages position %d%s', i, M_G_gsm(1), M_G_gsm(2), gsm, positionnumber,positionletter(pos)))

Make any necessary changes to get the result you want. When it works the way you want it to, make similar changes to your other title calls.

This worked wonders, THANK YOU! :) Im learning so much from this forum, its great!
