Change the Data That Is Used in a Shared-Variable Graph

After you have created a shared-variable graph, you can specify different data variables in the same or in a different data set. You make this change in the Assign Data dialog box for any of the plots in the graph, and the change is propagated to all plots in the graph.
To change the shared variables:
  1. Right-click inside the plot area of a cell in the graph, and select Assign Data.
    The Assign Data dialog box appears.
  2. Click the Shared Variables tab.
  3. If you want to change the SAS library or data set, select the appropriate items from the Library and Data Set list boxes.
    If you change the library or data set, the labels for one or more shared variables might appear red. This color indicates that a shared variable is being used in a plot and that you must reassign a data variable. In this display, the labels for V1 and V2 are red.

  4. To reassign a data variable to a shared variable:
    1. For each shared variable that you want to reassign, select the data variable from its Variable list box.
      The variables available in the list box depend on the variable type. For example, if the type is Numeric, then only numeric variables are listed. For a type of Any, all variables are listed.
    2. Select a variable type from the Type list box.
      You cannot change the data type if the variable is being used by any plot in the graph. The Type list box is dimmed to restrict assignment to like variables. For example, if V2 is being used in a histogram, then only a numeric variable can be chosen.
    3. Repeat the previous steps for each shared variable.
  5. To add a new shared variable, click the Add a Variable icon Add a Variable icon and then assign a data variable and type to the new shared variable.
  6. To remove a shared variable that you have added, click the variable to select the row. For example, click V3 to select a shared variable named V3.

    Then click the Delete a Variable icon Delete a Variable.
    Note: You cannot delete a shared variable that is currently used by any of the plots in the graph.
  7. Click OK.
Note: If you want to assign different shared variables to the variable roles in a plot, you can make this change in the Plot Variables tab of the Assign Data dialog box for the plot. If the cell contains more than one plot, select each plot from the Plot list box and assign shared variables. Assigning shared variables is similar to assigning data variables.
