HISTOGRAM Statement
- ENDPOINTS
- ENDPOINTS=value-list
-
specifies that histogram interval endpoints, rather than midpoints, are
to be aligned with horizontal axis tick marks.
If you specify ENDPOINTS=value-list, the
values must be listed in increasing order
and must be evenly spaced. The number of endpoint values is one
greater than the number of intervals in the resulting histogram.
The first value is the lower bound of the first interval
and the last value is the upper bound of the last interval.
If the range of the values does not cover the range of the data
and any specification limits (LSL and USL) that are given,
the list is extended in both directions as necessary to cover these values.
If you specify ENDPOINTS, the procedure determines the
number of intervals using the method of Terrell and Scott (1985),
with interval boundaries at horizontal axis tick mark values.
- NENDPOINTS=value
-
specifies the number of endpoints for histogram intervals, which is
equal to the number of intervals plus one.
If you specify the NENDPOINTS= option you do not need to specify the
ENDPOINTS option.
- NMIDPOINTS=value
-
specifies the number of midpoints for histogram intervals.
