I dont know if it has been always this way; but for a long time for me, Dia 
begins showing a region of diagram with the (0,0) point  at 'up' and 'left' 
position (sorry for my English). And Linbo's diagram has all its points with 
negative ordinates: all above the shown region.

Instead of changing the format of diagram files adding view information,  
the minimum  x (x0) and the minimum y (y0) of bouncing boxes of objects 
could be calculated; and then use (x0-delta,y0-delta ) instead of (0,0)
