#!CSeaGreen #!N  #!Rall295 Using a 
Data-Driven Sequencer #!N #!EC #!N #!N The Sequencer can be  #!F-adobe-times-medium-i-normal--18*   
data driven #!EF , meaning that its minimum, maximum, and step 
values can be set by connecting the output of a tool 
to the input of a Sequencer in the VPE or by 
a value typed into the Sequencer's Configuration dialog box, rather than 
by using the  #!F-adobe-times-bold-r-normal--18*   Frame Control #!EF panel. #!N #!N If 
the Sequencer is data driven, then the information transmitted by connection 
or set in the Configuration dialog box overrides values set in 
the  #!F-adobe-times-bold-r-normal--18*   Frame Control #!EF panel. #!N #!N A data-driven Sequencer 
allows you to create visual programs that will work with a 
variety of input data sets without your having to reset Sequencer 
attributes. For example, if the Sequencer minimum is set to zero 
and its maximum to the number of steps in a series, 
it can be used to drive the Select module to select 
each member of the series in turn. #!N #!N The inputs 
are summarized in the corresponding module description in IBM Visualization Data 
Explorer User's Reference. #!N #!N Each time an input to a 
data-driven Sequencer is changed (for example, by importing a new data 
set) the Sequencer is reexecuted, updating its attributes. #!N #!N #!N
