              pull-down menu. Y-axis scaling applies only to data currently selected 
              from the Trace field.

             AutoScale 
              button-- Automatically scales the vertical, Y-axis of the display 
              pane according to the range of data points plotted within the space 
              afforded by the user-sized window. Selection of this menu item disables 
              the YScale and YOffset fields (see "YScale 
              and YOffset Fields" sections above).
