Hi folks. I have another formatting question. I want to place a text box in a 3D plot. I have the following code where I calculate ResTime and then create a character string with it. I then issue the text command and I want the text box to have two lines, reading as such:
Particle residence
time=0.10s
Here's my code (minus the rest of the plotting commands). It won't work though. It'll create the first line of the text box, but not the second.
ResTime=L/U_f(1,3); %equals 0.10
str_textbox=sprintf('time=%4.2f s',ResTime);
text(.01,.01,.01,sprintf('Particle residence \n', str_textbox));
Thanks in advance,
M Ridzon

Combine both lines in one sprintf call to print a two-line text:
ResTime = 0.10;
figure(1)
plot(rand(1,5)-0.5, rand(1, 5)-0.5, 'pg')
text(.01,.01,.01,sprintf('Particle residence \ntime=%4.2f s',ResTime));
If I understand what you want to do, this should work.
