A dataset must be mapped to the Main Mappings panel once the action is defined for the first step. All subsequent steps will automatically be mapped to the same dataset. To map the data, drag the dataset from the Data folder to the Setup tab or use the 
icon in the Setup tab.
Use the option buttons in the Mappings panels to assign the columns in the dataset to the appropriate context associations. Required context mappings are colored orange. Context associations depend on which transformation type is selected in the Options tab.
None: Columns mapped to this context are simply included in the output.
x Column and y Column: Columns in a worksheet used in an Arithmetic transformation.
x Column: The independent variable that is used to compute the Baseline values or provide values for the Function transformations.
Sort: Sort variable(s) used to define individual profiles for Baseline transformations.
Time: Time values that are used to compute the Baseline values.
For Custom transformations, other mapping contexts are defined by entries in the Formula field.
Output Column:
None: Units of columns mapped to this context are ignored.
Unit: The column whose units are to be used in the new output column.
