I don't think that description is entirely well-defined. 
What if two rectangles overlap only partially?

It seems like perhaps what you need to do is to treat time as a
sequence of discrete intervals (1 second?), and rather than drawing
a rectangle per se, add the instantaneous flow to a running total in
the appropriate bins.  Then you could plot the bins in gnuplot with
the style "impulses".
