<DL>
<DD>Sets the interval position factor.  This controls how the interval is
 aligned to the x-value.  For a value of 0.5, the interval is aligned
 with the x-value in the center.  For a value of 0.0, the interval is
 aligned with the x-value at the lower end of the interval, and for a 
 value of 1.0, the interval is aligned with the x-value at the upper
 end of the interval.
 
 Note that changing the interval position factor amounts to changing the 
 data values represented by the dataset.  Therefore, the dataset that is
