Display a one-dimensional spectrum representation without clearing the graphic screen (overlay)
Name or number of an analyzer with one or more dimensions.
If omitted, the last specified analyzer is assumed.
Qualifier name or number. If omitted, the last specified qualifier is assumed.
Two pairs of x-values of the overlay
(o1,o2) and the
(b1,b2) spectrum. The overlay spectrum segment
is adjusted to the previous display such that the
corresponding x-coordinates are matching.
Constant which is added to the x-coordinates of the
Factor by which the x-coordinates of the overlaid spectrum are multiplied.
The calibration values specified with xoff and xfac are
ignored, if x-coordinates for adjustment are explicitly
Constant which is added to the y-values of the overlaid
Factor by which the overlaid spectrum data are multiplied.
Spectrum segment to be displayed, specified by
A limit omitted in the number list is replaced by the
actual value (or the analyzer limit, initially). An
* : analyzer limits (replaceable default)
- letter : display window identifier
# : temporary window
- one number : analyzer condition number
- number list : lower and upper limits
for the displayed dimension
*) means the corresponding analyzer limit.
Lower limits smaller or upper limits larger than the
corresponding analyzer limit are reset to the latter.
The limits are not modified to match with the bin borders.
If a reference to a calibration
'c' exists for a displayed
dimension (see display commands
the analyzer command
number list for this dimension refers to
'c' (and not
to the analyzer channel numbers).
If the analyzer has more than one dimension, and if a
display window or condition number is specified, only
the limits of the actually displayed dimension are
taken from 'w'. The display window or condition limits
of the NOT DOVERLAYED dimension(s) are used as projection limits.
For analyzers with more than one dimension only: the
analyzer dimension to be displayed (onto which will be
Replacable default: the first dimension.
Display bin size. Independent of the display limits,
bins are added always starting with the first analyzer
Default: the analyzer bin size.
Number defining the type of spectrum representation.
Valid types are:
Replaceable default is
- 0 no spectrum
- 1 single markers
- 2 polygon line
- 3 polygon line with markers
- 4 vertical lines
- 5 polygon histogram
- 6 polygon histogram with vertical lines
t=5 (polygon histogram).
Spectra are drawn with error bars, if defined previously by the

With the keywords
logical number between 1 and 10 is expected, which refers to the attributes look-up table.
DATTR for the graphic attributes assigned
to these numbers.
Debug switch. Lots of output !
When changing the displayed dimensions
for analyzers with more than one dimension, previous
display limits are not taken as new projection limits,
and vice versa.
If the primary display was done with a calibrated axis,
the number list specified with the
refers to this calibration.
If a list of attributes is specified, the values are
kept and cyclically assigned to the next overlays,
which are drawn into the same picture.
The graphic attributes may be specified using global
DOVE A1 200 100 500 700 / YFAC(10)
Display the spectrum of analyzer
A1 over the already
drawn spectrum. Channel no 200 of the overlay spectrum
is located in the position of channel no 100 of the
previous spectrum on the x-axis, and channel no 500 of
the overlay in the position of channel no 700 of the
Additionally, the contents of the displayed channels of
the overlay spectrum are multiplied by a factor of 10
