Could anybody help me with this please? I would like to draw a 3D graph consists of 3 different sizes of function. e.g. the size of the first function is (6,12),the size of the second function is (6,16) and the size of the third function is (6,22). The three functions are not related,however,I am hoping they can be represented in the same graph and using the same axis scale. Thanks in advance.

I will assume that by "size" you mean the range of the output (the z variable) and you are plotting a line using plot3. If you type hold on after your first plot, the next two plots will adjust the scale appropriately so all three curves are displayed.

My speculation would be that zhe is wanting to do surface plots, using surf(). "hold on" is the general solution for that too -- but the surfaces will usually mix together unless special care is taken.

Yup, surf alright.
