Information about histograms

Four options ( HPLOPT)are available to plot additional informations on HPLOT pictures: DATE, FILE, STAT and FIT.
* Plot date and hour on current HPLOT picture
      CALL HPLOPT('DATE',1)
* Plot file name of current histogram
      CALL HPLOPT('FILE',1)
* Plot statistics of current histogram
      CALL HPLOPT('STAT',1)
* Plot Fit parameters of current histogram
      CALL HPLOPT('FIT ',1)
For each of these option a corresponding HPLSET parameter is available:
      CALL HPLSET('DATE',r)
      CALL HPLSET('FILE',r)
where r defines the position of the date or file name:
r = 1.
Top left corner of page/current histogram (default for file).
r = 2.
Top right corner of page/current histogram (default for date).
r = 3.
Bottom left corner of page/current histogram.
r = 4.
Bottom right corner of page/current histogram.
For example the call:

      CALL HPLSET('DATE',3.)
sets the position of the date to the bottom left corner of the HPLOT pictures.
      CALL HPLSET('STAT',r)
where r corresponds to binary status bits OURMEIA as follows:
O=1
Draw number of overflows
U=1
Draw number of underflows
R=1
Draw R.M.S.
M=1
Draw mean value
E=1
Draw number of entries
I=1
Draw histogram identifier
A=1
Draw the contents of all channels
For example the call:
      CALL HPLSET('STAT',10.)
sets the statistics informations to be only the number of entries.
      CALL HPLSET('FIT ',r)
where r corresponds to binary status bits CEP as follows:
2
C=1
Draw chi
E=1
Draw errors
P=1
Draw fit parameters
2 For example to draw only the result of the chi fit one would use:
      CALL HPLSET('FIT ',100.)
For all these options, the character size is specified with the HPLSET parameter 'CSIZ' and the character font used with the parameter 'CFON'.
