Chinh,<div>Use the draw string, draw mark, draw line, and draw rec or draw recf commands. You need to supply those commands with x and y coordinates of the endpoints of the line, a reference point for the string, or corners of the box. You can obtain those either by entering q pos and clicking on the screen where you want to get coordinates, then saving the output that comes from that, or by using q w2xy a b, where a and b are the phase coordinates (in your case, time and temperature are the coordinates), and saving the output from that. </div>
