Purpose
Display (parts of) analyzer spectra with two or more
dimensions in a two-dimensional representation.
Parameters
anl
-
Name or number of an analyzer with two or more dimensions.
If omitted, the last specified analyzer is assumed.
evt
-
Qualifier name or number. If omitted, the last specified qualifier is assumed.
dim(dimlist)
-
Analyzer dimensions to be displayed
(onto which will be projected).
Replacable default:
dimlist=1,2
.
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 key word CALIB(c)
or
command
AMOD
), the number list for this dimension
refers to 'c'
(and not to the analyzer channel numbers).
If the analyzer has more than two dimensions, 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 displayed dimension(s) are used as projection limits.
bins(binlist)
-
List of display bin sizes.
Independent of the display limits,
bins are added always starting with the first analyzer
bins.
Default: the analyzer bin sizes.
lin
-
Linear data axis.
log
-
Logarithmic data axis.
sqrt
-
Square root data axis.
calib(c)
-
If once given, the values for the x-axis and the x-axis
description are taken from the calibration
'c'
.
'c'
consists of two names
'cname.cqual'
. If 'cqual'
is
omitted, 'CAL'
is assumed. A reference between the
calibration and the corresponding analyzer dimension is
created and remains valid for subsequent D2
commands.
Not yet implemented
xnocal
-
ynocal
-
The reference to the calibration
'c'
- if existing -
will be ignored for the current command.
isometric
-
Isometeric plot. Not yet implemented.
contour
-
Contour plot.
cluster
-
Cluster plot with differently sized clusters.
area
-
Area filling cluster plot. Useful only in colours.
scatter
-
Scatter plot.
Replaceable default is cluster
.
format(r)
-
Ratio of width and height of the spectrum, defined by
the length of the corresponding axes. Allowed values
are in the range between r = 0.4 and r = 1.7. If
r > 1.4, there is no space for informations on display
windows and points right of the spectrum display.
Replaceable default is r = 1.4.
colours(clist)
-
List of colour indices.
Replaceable default is
clist = "5,6,4,8,3,7,1"
.
widths(wlist)
-
List of width indices. Replaceable default is
wlist = 1
.
linetypes(llist)
-
List of line type indices. Replaceable default is
l = 1
.
With the keywords
colours
,
widths
,
linetypes
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.
zscale(zlim)
-
Pair of values specifying the range of data values to be displayed.
A
"*"
denotes a limit taken from the spectrum itself,
an omitted value defaults to the last used limit.
ncuts()
-
Number of cuts in z-direction to be displayed.
Effective only if no
cuts()
are specified.
cuts()
-
List of cut values for
contour
or cluster
plot.
debug
-
Debug switch. Lots of output !
Function
Remarks
Examples
Analyzer segment, projections
D2 3 2 / ZSCALE(1,*) LOG CLU
Display analyzer no. 3 with qualifier no. 2 within the
analyzer limits (startup default).
If the analyzer has more than two dimensions,
the complete analyzer range of the third (and possibly
higher) dimension(s) is projected onto the x-y-plane.
Data from 1 up to the maximum spectrum count are considered.
A cluster representation with logarithmic spacing is plotted.
