Hi Yu,
You could shift your positive numbers down by two, plot those adjusted 
numbers without an x axis, and finally display a custom x axis for which 
-1 and +1 were at the same point and the positive tick marks were 
adjusted back up. I don't think this is a very good idea, though, as the 
idea of most illustrations is to convey information to the viewer 
without the producer being present to explain what happened to the 
number scale. I thought of adding axis breaks on the top and bottom of 
the above at +-1, but I'm not sure that it will be much of an 
improvement. I assume that the -1 to +1 gap is a substantial part of 
your x axis, i.e. you aren't really plotting -Inf to Inf (in which case 
your gap would be infinitely small).
