   I don't really understand. The size of this figure is the size of the 
line inside it. Isn't it? So the bounding box is

There is only one (syntaxic) error in this code: subgriddiv isn't a 
dimension: subgriddiv=1in is an error. subgriddiv indicates the number 
of subdivisions in one division, here you have to say
