i have read it, and i didn't found the answer. Its's why i post here.
I found this :
Graphically Displaying Lists
If you have Graphical Data Display Manager (GDDM) installed and have a terminal capable of displaying graphics, you can display lists of applications, occurrences, and operations graphically. Graphic displays contain the same information as edit or selection lists, only the format is different. On a graphically displayed list, you can see dependency connections that might be difficult to visualize from a conventional list. An entire network of applications can be represented.
To see a graphically displayed list, enter GRAPH at the command prompt of a panel on which graph is an option. The clarity of the graph depends on how much data GDDM is trying to present on your display terminal. For example, if you request a GRAPH of all operations in the current plan, you would probably see an attractive geometric design that resembles a bunch of grapes: there is simply too much data to present graphically on a standard workstation display terminal.
You can use the GDDM command to display the GDDM menu where you can choose the zoom and print functions. With GDDM Version 3, you can print a zoomed area. Before printing, change the colors so that you have a black-and-white image. It is often useful to save the graph in the ADMGDF format, which you can manipulate with other programs.
The attributes of a graphically displayed list can be customized. Enter ATTR at the command prompt from the graph panel. You can specify the color, shape, and line type for different items displayed in the graph. Press PF1 (HELP) for possible values for the attributes.
But i still have no answer about my problem.
