Purpose

Mark windows in the current one-dimensional spectrum display and write the sum of counts into the graphic screen

Parameters

w1 w2

Window identifiers. The windows from 'w1' to 'w2' in alphabetic order are marked and evaluated. Valid window identifiers are If 'w2' is omitted, only window 'w1' is affected. If 'w1' and 'w2' are omitted, the window of the last specified type (analyzer condition or display window), following the previous one in numerical or alphabetic order, respectively, is marked.

static

For n-dimensional analyzers with n > 1 only: the access mode requested when summing up the counts within the window(s). In the static mode, the window limits for all dimensions are taken from the window data structure, independent of the actual projection limits. Default: The dynamic mode. In this mode, a display window corresponds to a display window of a one-dimensional spectrum. Its contents is evaluated by summing up the displayed spectrum counts between the corresponding limits in the displayed dimension.

all

The spectrum is displayed with the analyzer limits, and each specified window is marked.
Not yet implemented.

expand

If only one window ('w1') was specified: the spectrum segment defined by this window is shown.
If all or expand was specified, the displayed dimension and the projection limits - if relevant - are not affected and taken from the previous display.
If all and expand are omitted, the required window(s) are marked in the actual display, and the following keywords are meaningless.
Not yet implemented.

lin

Linear y-axis.

log

Logarithmic y-axis.

sqrt

Square root y-axis.
If neither LIN, LOG nor SQRT is specified, the y-axis refers to the global mode. Startup default is a linear y-axis.

auto

Automatic y-scaling.

fix

Fixed y-scaling.
If AUTO and FIX are omitted, y-scaling is determined by the global mode. Startup default is automatic scaling.

debug

Debug switch. Lots of output !

Function

Remarks

For n-dimensional display windows or conditions two modes are available: For one-dimensional analyzers, there is no difference between the static and the dynamic mode.
The contents of a display window or a condition is independent of the actual display bin size.

Examples

DGW  3  N / ALL
The whole spectrum is redrawn and all windows identified by numbers greater or equal than 3 (conditions) and letters up to N (display windows) are marked. Their contents is individually summed up and displayed on the graphic screen.
If the current analyzer has more than one dimension, the currently displayed dimension will be redrawn with the current projection limits. The contents of the specified conditions and windows is evaluated in dynamic mode by summing up the displayed counts within the corresponding limits. 
DGW  3  N / ALL
The same windows as in the previous example are marked and evaluated in static mode. As projection limits, however, the limits from the window data structures (and not from the actual display environment) are used. 
DGW / EXP
In the previous example, the last window accessed was the display window N (if existing). So the spectrum is redrawn within the limits of the next available display window, which may be O, e.g., or A ! In case of an n-dimensional analyzer, the displayed dimension and the projection limits remain valid.
