How to use the command

1. Type L from the Graph Options menu.
2. Specify the data range (A-F) to be identified with a legend. This prompt is displayed:
   Enter the legend for x :
   where x is one of ``A'', ``B'', ``C'', ``D'', ``E'', or ``F''.
3. Type the legend you want to identify the range with and then press RETURN. You can use up to 39 characters.
4. Xspread then returns you to the Graph Options Legend menu. To exit the Graph Options Legend menu, press the ESC key.
   If you want to create more than one legend, select another menu item. When you display the graph, it will have the legend that you specified.
   CAUTION: When you select a legend data range, xspread does NOT retain any previously defined legend for that data range. Instead, xspread erases any previously defined legend.
