In SAS Enterprise Guide 4.1, there is no Right Vertical axis Task role
for the graph type 'Multiple vertical column line plots using overlay'.

Here is one method to circumvent the problem:

   1. Select Tools => Options => Tasks => Tasks General => change
      'Filter unused variables' to Never => Ok.
   2. Assign the columns and make any other selections you like.
   3. From the Line Overlay task, click 'Preview Code' and
      then 'Insert Code'.
   4. Scroll down to the section just after the following line:

      'Overlay vaxis=axis1 haxis=axis2 frame legend=legend1

   5. Double-click the line that shows: 'double-click to insert code'
      This will bring up a window 'Enter User Code'.
   6. Enter code similar to the following. Note the leading and
      ending semicolon (;).

      ;plot2 your_right_vertical_var * your_horizontal_var;

   7. Click OK to close.
   8. Click OK to close the 'User code' window.
   9. Click the 'X' to close the 'Code preview for task' window.
  10. Run the task.
