this is a very simple question ... hopefully someone has a quick answer.
suppose I define a simple graphics object and display it ... for example ...
obj = Line[ { {-3, -1}, {3, -1} } ] ; Graphics[obj]
these 2 lines of code work fine - and I get a Line in Mathematica.
Now ... I want to do the same thing inside a loop, such as a For Loop. But Mathematica gives no output. WHY?? Even if I add a Show command outside the Graphics statement, this still does not work.
For [ j = 1, j < 3, j++, Graphics[obj]
]
thanks, Pete
