Purpose
Display a one-dimensional spectrum representation without clearing the graphic screen (overlay)
Parameters
anl
-
Name or number of an analyzer with one or more dimensions.
If omitted, the last specified analyzer is assumed.
evt
-
Qualifier name or number. If omitted, the last specified qualifier is assumed.
o1
-
b1
-
o2
-
b2
-
Two pairs of x-values of the overlay
(o1,o2)
and the
basic (b1,b2)
spectrum. The overlay spectrum segment
is adjusted to the previous display such that the
corresponding x-coordinates are matching.
xoff(x)
-
Constant which is added to the x-coordinates of the
overlaid spectrum.
Default:
x=0
.
xfac(f)
-
Factor by which the x-coordinates of the overlaid spectrum are multiplied.
Default:
f=1
.
The calibration values specified with xoff and xfac are
ignored, if x-coordinates for adjustment are explicitly
given.
yoff(y)
-
Constant which is added to the y-values of the overlaid
spectrum.
Default:
y=0
.
yfac(g)
-
Factor by which the overlaid spectrum data are multiplied.
Default:
g=1
.
window(w)
-
project(w)
-
Spectrum segment to be displayed, specified by
-
*
: 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
A limit omitted in the number list is replaced by the
actual value (or the analyzer limit, initially). An
asterisk (*
) 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
DISPLAY/CALIB(c)
and
D2/CALIB(c)
or
the analyzer command
AMOD
), the
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.
dim(d)
-
For analyzers with more than one dimension only: the
analyzer dimension to be displayed (onto which will be
projected).
Replacable default: the first dimension.
bins(b)
-
Display bin size. Independent of the display limits,
bins are added always starting with the first analyzer
bin.
Default: the analyzer bin size.
type(t)
-
Number defining the type of spectrum representation.
Valid types are:
- 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
Replaceable default is t=5
(polygon histogram).
error
-
Spectra are drawn with error bars, if defined previously by the
command
AERROR
.
noerror
-
No error bars are drawn.
If error
and noerror
are omitted, the global error
mode is in effect
(see display command DMODE
). Initially
no error bars are drawn.
colour(c)
-
Colour number. Replaceable default is
c=1
.
width(w)
-
Width number. Replaceable default is
w=1
.
line(l)
-
Line type number. Replaceable default is
l=1
.
marker(m)
-
Marker number. Replaceable default is
m=1
.
With the keywords
colour
,
width
,
line
, and
marker
,
a
logical number between 1 and 10 is expected, which refers to the attributes look-up table.
See the
command DATTR
for the graphic attributes assigned
to these numbers.
debug
-
Debug switch. Lots of output !
Function
Remarks
When changing the displayed dimensions
(keyword dim(d)
)
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
window
option also
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
parameters.
Examples
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
old one.
Additionally, the contents of the displayed channels of
the overlay spectrum are multiplied by a factor of 10
(for the display only).
DOVE A / TYPE(5) COL(2..4)
DOVE B
DOVE C
Analyzers A
, B
, and C
are overlaid on the current display,
represented by polygon histograms with colours 2,
3, and 4.
