Functional Details #!N #!N This interactor provides incremental control of various 
functions in a visual program (e.g., the number of contour lines 
currently displayed on an isosurface in the Image window). The integer 
range over which the module acts is governed by its attributes 
(e.g., minimum, maximum, and delta), which in turn are either (1) 
specified by the parameter values in its  #!F-adobe-times-bold-r-normal--18*   Set Attributes... #!EF 
dialog box or (2) determined from input to the module (e.g, 
a data field). In the second case, the interactor is said 
to be "data driven." #!N #!N Note: The interactor is invoked 
by double-clicking on its icon in the VPE window. Its configuration 
dialog box is accessed from the  #!F-adobe-times-bold-r-normal--18*   Edit #!EF pull-down menu 
in the same window. #!N #!I0 #!N #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   
 #!F-adobe-times-bold-r-normal--18*   data #!EF #!EF #!I50 #!N is the object (usually a 
data field) from which the interactor can derive any or all 
of the minimum, maximum, and delta attributes when the corresponding input 
tabs are up. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   refresh #!EF #!EF 
#!I50 #!N resets the interactor so that the output is computed 
from the current input. If  #!F-adobe-times-bold-r-normal--18*   refresh #!EF = 0 (the 
default), the output is recomputed only if the current output does 
not lie within the range of the current  #!F-adobe-times-bold-r-normal--18*   data #!EF 
. The default for the output of the interactor is the 
midpoint of  #!F-adobe-times-bold-r-normal--18*   min #!EF and  #!F-adobe-times-bold-r-normal--18*   max #!EF . #!N 
#!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   min #!EF  #!F-adobe-times-medium-r-normal--18*   and #!EF  #!F-adobe-times-bold-r-normal--18*   max 
#!EF #!EF #!I50 #!N specify the minimum and maximum values of 
the interactor's integer output. If set, these values override those implied 
by  #!F-adobe-times-bold-r-normal--18*   data #!EF . #!N #!N If neither  #!F-adobe-times-bold-r-normal--18*   min 
#!EF nor  #!F-adobe-times-bold-r-normal--18*   data #!EF is specified, the interactor uses the 
minimum set in the  #!F-adobe-times-bold-r-normal--18*   Set Attributes... #!EF dialog box. #!N 
#!N If neither  #!F-adobe-times-bold-r-normal--18*   max #!EF nor  #!F-adobe-times-bold-r-normal--18*   data #!EF is 
specified, the interactor uses the maximum set in the  #!F-adobe-times-bold-r-normal--18*   Set 
Attributes... #!EF dialog box. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   delta #!EF 
#!EF #!I50 #!N specifies a scalar value as a factor for 
calculating the increment between successive outputs over the specified range. The 
actual value depends on the interpretation specified by  #!F-adobe-times-bold-r-normal--18*   method #!EF 
(see below). #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   method #!EF #!EF #!I50 
#!N specifies the interpretation of  #!F-adobe-times-bold-r-normal--18*   delta #!EF : #!N #!I0 
#!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 #!N o "rounded": the increment ( 
 #!F-adobe-times-bold-r-normal--18*   max #!EF -  #!F-adobe-times-bold-r-normal--18*   min #!EF ) *  #!F-adobe-times-bold-r-normal--18*   delta 
#!EF is rounded to a "nice" number. The spacing between successive 
values will approximate the interval specified by  #!F-adobe-times-bold-r-normal--18*   delta #!EF . 
(For example, the default value of 0.01 specifies an interval of 
1/100 of the specified range.) #!N #!I30 #!N o "relative": the 
interpretation is the same as for "rounded," but the increment is 
 #!F-adobe-times-medium-i-normal--18*   not #!EF rounded. #!N #!I30 #!N o "absolute":  #!F-adobe-times-bold-r-normal--18*   delta 
#!EF is the absolute value of the interval. (If  #!F-adobe-times-bold-r-normal--18*   delta 
#!EF has not been specified, its default is 1.) #!N #!N 
The default value for  #!F-adobe-times-bold-r-normal--18*   method #!EF depends on other input. 
The default is: #!N #!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 #!N 
- "rounded" if  #!F-adobe-times-bold-r-normal--18*   data #!EF is specified  #!F-adobe-times-medium-i-normal--18*   or #!EF 
if both  #!F-adobe-times-bold-r-normal--18*   min #!EF and  #!F-adobe-times-bold-r-normal--18*   max #!EF are specified. 
#!N #!I30 #!N - "absolute" in all other cases. #!N #!I0

 #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   label #!EF #!EF #!I50 #!N is the global label 
of all instances of the corresponding interactor stand-in. An interactor instance's 
local label (set from the Control Panel) overrides a global label. 
By default, the global label is set by the user interface.
