#!F-adobe-helvetica-medium-r-normal--18* #!N #!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 #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Lermsgs,dxall297 h Error Messages #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
