#!F-adobe-helvetica-medium-r-normal--18* #!N #!CSeaGreen #!N #!Rcatstr Structuring #!N #!EC #!N #!N These tools manipulate Data Explorer data structures. Their functions include the creation of hierarchies, selection of elements in a hierarchy, allowing operations on components other than "data," manipulation of Field or Group components, and determining which branches of a visual program are to be executed. #!N #!I0 #!N #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Lappend,dxall767 h Append #!EL #!EF #!I50 #!N Adds Objects as members to an existing Group. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Lattrib,dxall769 h Attribute #!EL #!EF #!I50 #!N Extracts an attribute from an Object. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Lchggrme,dxall784 h ChangeGroupMember #!EL #!EF #!I50 #!N Inserts, renames, or deletes a member of an existing Group. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Lchggrty,dxall785 h ChangeGroupType #!EL #!EF #!I50 #!N Changes the type of a Group. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Lcollect,dxall788 h Collect #!EL #!EF #!I50 #!N Collects Objects into a Group. For example, you can use Collect to collect a streamline, an isosurface, and a light. You can then pass the collection to the Image tool. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Lmultigr,dxall789 h CollectMultiGrid #!EL #!EF #!I50 #!N Collects Objects into a Multigrid (a Group that will be treated as a single data Object). #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Lcollecn,dxall790 h CollectNamed #!EL #!EF #!I50 #!N Collects Objects into a Group (like Collect) but allows each Object in the Group to be given a name. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Lcollecs,dxall791 h CollectSeries #!EL #!EF #!I50 #!N Collects Objects into a Series. You give each element of the series a series position (e.g., a time tag). #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Lcopycon,dxall800 h CopyContainer #!EL #!EF #!I50 #!N Copies the top container Object. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Lextract,dxall845 h Extract #!EL #!EF #!I50 #!N Extracts a component from a Field (e.g., the "colors" component). #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Linquire,dxall877 h Inquire #!EL #!EF #!I50 #!N Returns information about the input Object (e.g., data type, number of elements, etc.). #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Llist,dxall885 h List #!EL #!EF #!I50 #!N Concatenates several items into a single list. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Lmark,dxall893 h Mark #!EL #!EF #!I50 #!N Marks a specified component in a Field as the data component. Many modules operate only on the "data" component. Thus the Mark module allows modules to operate on components other than data (e.g., "positions" or "colors"). If a "data" component already exists, it is preserved in a "saved data" component. You can restore it by using the Unmark module. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Loptions,dxall898 h Options #!EL #!EF #!I50 #!N Associates attributes with an Object. For example, plotting options such as marker type can be specified by adding attributes to the line. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Lremove,dxall921 h Remove #!EL #!EF #!I50 #!N Removes a specified component from a Field. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Lrename,dxall922 h Rename #!EL #!EF #!I50 #!N Renames a component in a Field. For example, you could rename the "colors" component to "front colors" to get only front-facing colors. You should be aware that component names have special meanings to modules using them. See #!Ldatmod,dxall197 h Understanding the Data Model #!EL in IBM Visualization Data Explorer User's Guide. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Lreplace,dxall925 h Replace #!EL #!EF #!I50 #!N Replaces a component in one Field with a component from another, or with an input Array. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Lselect,dxall936 h Select #!EL #!EF #!I50 #!N Selects members out of a Group or elements from a list. two isosurfaces, a streamline, and a mapped plane. You could then use the #!F-adobe-times-bold-r-normal--18* selector #!EF input to the module to choose which of these is the output of the module. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!Lunmark,dxall972 h Unmark #!EL #!EF #!I50 #!N Undoes the action of the Mark module. It moves the "data" component back to the component you specify, and the "saved data" component is restored to the "data" component. #!I0 #!N #!N #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Lcattrn,dxall763 h Transformation #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
