Each 1-dimensional histogram output consists of several parts, some compulsory and some optional:
| general title | compulsory (if defined) |
| identifier, date and title | compulsory |
| the histogram itself | default = yes |
| channel numbers | default = yes |
| channel contents | default = yes |
| error values | default = no |
| value of the superimposed function (if any) | default = no |
| integrated contents | default = no |
| low edge of channels | default = yes |
| statistical information | default = yes |
Routine HIDOPT can be used to change the above defaults.
Action: Select an option for a given histogram.
ID=0 the option is set for all histograms.
.)
| Option | Action |
| SETD* | Set all options to the default values |
| SHOW | Print all the options currently set |
| BLAC | 1 Dim histogram printed with X characters (see HPCHAR) |
| CONT* | 1 Dim histogram is printed with the contour option |
| STAR | 1 Dim histogram is printed with a * at the Y value (see HPCHAR) |
| SCAT* | Print a 2 Dim histogram as a scatter-plot |
| TABL | Print a 2 Dim histogram as a table |
| PROS* | Plot errors as the Spread of each bin in Y for profile histograms |
| PROE | Plot errors as the mean of each bin in Y for profile histograms |
| STAT | Mean value and RMS computed at filling time (double precision) |
| NSTA* | Mean value and RMS computed from bin contents only |
| ERRO | Errors bars printed as SQRT(contents) |
| NERR* | Do not print print error bars |
| INTE | Print the values of integrated contents bin by bin |
| NINT* | Do not print integrated contents |
| LOGY | 1 Dim histogram is printed in Log scale in Y |
| LINY* | 1 Dim histogram is printed in linear scale in Y |
| PCHA* | Print channel numbers |
| NPCH | Do not print channel numbers |
| PCON* | Print bin contents |
| NPCO | Do not print bin contents |
| PLOW* | Print values of low edge of the bins |
| NPLO | Do not print the low edge |
| PERR | Print the values of the errors for each bin |
| NPER* | Do not print the values of the errors |
| PFUN | Print the values of the associated function bin by bin |
| NPFU* | Do not print the values of the associated function |
| PHIS* | Print the histogram profile |
| NPHI | Do not print the histogram profile |
| PSTA* | Print the values of statistics (entries,mean,RMS,etc.) |
| NPST | Do not print values of statistics |
| ROTA | Print histogram rotated by 90 degrees |
| NROT* | Print histogram vertically |
| 1EVL | Force an integer value for the steps in the Y axis |
| AEVL* | Steps for the Y axis are automatically computed |
| 2PAG | Histogram is printed over two pages |
| 1PAG* | Histogram is printed in one single page |
| 2lA star |'*'| indicates that the option is the default setting. |
List of available HBOOK options, which can be set by HIDOPT
If CHOPT='YES' statistics are computed at filling time.
All the histograms created (via HBOOK1 or HBOOK2) after a
CALL HSTAF('YES'), will have the IDOPT option
'STAT'STAT automatically activated.
This is very useful when histograms are created in an
indirect way like in the command NT/PLOT.
The way to activate this option in PAW is:
PAW > OPTION HSTA PAW > NT/PLOT 10.x IDH=100
