Graphic Choices (1-dimensional histogram)

A histogram is normally represented by drawing its contour, with a channel being represented by one character along the printed line at a displacement corresponding to the bin contents, but alternative graphic presentations are available. If some contents are negative a dotted line is drawn at Y=0.

CALL HPCHAR (CHOPT,CHAR)

Action: Selects a printing character different from the default for histograms that are not drawn contour only, or for superimposed functions.

Input parameters:

CHOPT

Printing option for which the character applies. It can be:

'BLAC'

when HIDOPT(ID,'BLAC')BLAC is called

'FUNC'

when HBFUN1, HFUNC or HIDOPT(ID,'STAR')STAR have been called.

'STAR'

when HBFUN1, HFUNC or HIDOPT(ID,'STAR')STAR have been called.

CHAR

Character chosen.

Example:

CALL HPCHAR ('STAR','.')

CALL HBIGBI (ID,NCOL)

Action: For a given 1-dimensional histogram prints one channel over a certain number of columns.

Input parameters:

ID

Histogram identifier

NCOL

Number of columns to be used per bin.
NCOL=0 meams use the full width of the page.

Remark:

• HBIGBI will be applied to histograms output across the page only, i.e. if NCHAN*NCOL$\le$ 100.
  If this relation is not fulfilled, then the value of NCOL will be reduced till it obeys the inequality. No restrictions if the histogram is printed down the page (HIDOPT(ID,'ROTA')STAR).
• If the histogram is 2-dimensional, the ``bigbin'' option is selected on all its projections, etc.
• It can be redefined at any time.
