If you have set the string to (x,y) , then for another string you can set it to (x, y+h) where h is the height for one character in the coordinate system for the simulation.
or, You can set those string to the same (x,y) and set different alignment property for those strings (lower right, upper right,lower left, upper left; 4 strings maximum) .
I hope you can understand what I was talking about.
Please try to solve it by yourself first. If you really can not make it work. Post you file again and I will modify it for you!
