XRange 
                and XOffset Fields
              
               The 
                XRange value controls the scale of the X-axis. As this 
                value is changed, plots are stretched and compressed horizontally; 
                simultaneously, X-axis units change at the bottom of the display 
                pane. XRange units of measurement depend upon whether MaxBuffer 
                (units in milliseconds) or Sample Size (units in samples) 
                is selected in the Pane / Display window. You may enter 
                XRange values in one two ways:
              
                -  Manual 
                  entry in the XRange field (click with cursor and enter 
                  value).
 
                -  Use 
                  of Zoom Bar functions.
 
              
               As 
                XRange is increased-decreased, X-axis units are rescaled 
                to fit the display pane.
                
               The 
                XOffset value controls which X-axis portion of the buffered 
                data (see "MaxBuffer" section above) is displayed 
                inside the pane. XOffset may be adjusted by moving the 
                slider bar left-right, or by entering a value into the XOffset 
                field manually.
