Data Explorer Tools #!N #!EC #!N #!N Data Explorer tools (i.e., 
tool modules) perform a variety of functions to generate visual images. 
In the VPE window, their icons can be used as "building 
blocks" to create visual program  #!F-adobe-times-medium-i-normal--18*   networks #!EF , from which 
images are generated in the Image window. They can also be 
invoked from script-language programs or from the command line (when Data 
Explorer is in "script mode"). And they can be grouped together 
in macros for greater efficiency. #!N #!N Many modules are accessible 
through both the graphical user interface and the scripting language. Some, 
however, are available only through the user interface: the Interactors, the 
Color Editor, Image, Pick, Probe, Receiver, and Transmitter. Most have default 
values for parameter inputs, values that are (as much as possible) 
appropriate for the data involved. These defaults enable the new user 
to begin visualizing data with only a few connections and to 
customize a visualization program one step at a time. #!N #!N 
Tools are divided into the categories listed in the top palette 
of the VPE window: #!N #!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 
#!N o Annotation #!N #!I30 #!N o DXLink #!N #!I30 #!N

Windows #!N #!I30 #!N o {ALL} (an alphabetic listing of all 
the tools). #!N #!I0 #!N #!EF #!N #!N #!N The directory 
 #!F-adobe-times-bold-r-normal--18*   /usr/local/dx/samples/programs #!EF contains visual program examples that use these tools, 
along with a subdirectory (...  #!F-adobe-times-bold-r-normal--18*   /SIMPLE #!EF ) of simpler 
examples. Use the  #!F-adobe-times-bold-r-normal--18*   Open #!EF file-selection dialog box to call 
up either directory (adding "/*.net" to the directory name when you 
enter it in the  #!F-adobe-times-bold-r-normal--18*   Filter #!EF text field). For a 
description of a visual program, either highlight the program name in 
the  #!F-adobe-times-bold-r-normal--18*   Files #!EF list of the dialog box and click 
on the  #!F-adobe-times-bold-r-normal--18*   Comments #!EF pushbutton or select the  #!F-adobe-times-bold-r-normal--18*   Application 
Comment #!EF option of the  #!F-adobe-times-bold-r-normal--18*   Help #!EF pull-down menu (after 
the visual program is loaded). #!N #!N The directory  #!F-adobe-times-bold-r-normal--18*   /usr/local/dx/samples/scripts 
#!EF contains script examples for all of the modules. Descriptions are 
included as comments in the script files themselves. #!N #!N The 
rest of this chapter summarizes the tool categories and the tools 
they contain. The order in which they appear is the same 
as that displayed in the palettes of the VPE window. For 
detailed descriptions of individual tools, see  #!Lfmd,dxall765 h Functional Modules  #!EL  . Note: Two modules 
that appear in  #!Lfmd,dxall765 h Functional Modules  #!EL  are available only in script mode and 
so are not listed in any of the Visual Program Editor
