Description:
This
routine find the set of (X,Y) values representing the centre of each bin in a given histogram.
The logarithm of the supplied values are used if logarithmic axes are requested. In this
case, zero or negative values result in VAL__BADR values being returned.
Invocation
CALL KPG1_HSTLO( NHIST, HIST, HMIN, HMAX, XLOG, YLOG, XLOC, YLOC, STATUS )
Arguments
NHIST = INTEGER (Given)
The number of bins in the histogram.
HIST(
NHIST ) = INTEGER (Given)
The histogram whose locus is to be found.
HMIN = REAL
(Given)
The minimum data value that could be included within the histogram.
HMAX =
REAL (Given)
The maximum data value that could be included within the histogram.
XLOG = LOGICAL (Given)
If .TRUE., logarithmic value are returned for the X axis.
YLOG = LOGICAL (Given)
If .TRUE., logarithmic value are returned for the Y axis.
XLOC( NHIST ) = REAL( WRITE )
Work array for the x locus of the histogram.
YLOC(
NHIST ) = REAL( WRITE )
Work array for the y locus of the histogram.
STATUS =
INTEGER (Given and Returned)
This is the status value on entry to this subroutine.
