Indeed that could be a factor. If so, it may be alleviated by setting
explicit x and y ranges on the first plot (overplots automatically
change the plot range to fit everything, unless the place where the
are overplotting had explicit ranges set). And by disabling refresh
during the overplots (as in p.refresh,/disable).
