Specifying Low and High values
The range of the X axis is determin ed by the Low value and High value
fields. To change the X axis range, select the Low value or High value
fields and enter new limits. The range you specified will then be
divided among the 256 available buckets along the X axis (unless the
range is less than 256 or the histogram frame is truncated due to
bucket range round-off).
For example, you might set the low and high values so that the range is
1100. 1100 divided by 256 is 4.29. This will be rounded up to 5, and
each bucket will have a range of 5. Because 1100 divided by 5 is 220,
the histogram frame will be truncated at the right because the X axis
will have only 220 of the 256 buckets.
