Hi Shane,
The halfwidth argument is used to set the width of bars if any are 
displayed. As the x units of a plot are often successive integers, the 
default halfwidth argument leaves spaces of about one fifth the width of 
the bars. If other explicit x values are passed, the spaces may be too 
narrow or the bars may overlap. It is up to the user to set halfwidth to a 
value that "looks nice".
