You can modify Xess graph options in two ways. One is by changing
the "New Graph Options" found under the "Options" menu of the main
sheet. You can also change the settings of a graph more specifically
by changing the options found under the "Edit" and "Options" menus in
the Graph Editor window.

Modifying General Options
-------------------------

The General Options dialog box allows you to define the following graph
characteristics:

                o Graph type
                o Automatic redraw after recalculation
                o Display legend
                o Default foreground and background color
                o Default font, style, size
                o Graph title text, font, style, size, color


To change general graph options:

1. Display "Options" from the Graph Editor menu bar.

2. Select the "General" option which displays the General Options dialog box.

3. Modify any of the following options accordingly:

  - Graph types:

        o Scatter graphs
        o Line graphs
	o Area graphs
        o Bar graphs
	o Stacked bar graphs
        o Histogram
        o Pie graph
        o Surface graph (3D rotation)
        o Contour graph
        o Polar graph
        o Hi-Lo graph
	o Control graph
	o Box graph


        Warning!!  Although it is easy to switch from one graph type
        to another the graph range selected may be incorrect or
        insufficient to create such a a graph.  In this even, a
        (sometimes cryptic) error message is displayed on the
        Control/Status area of the main window. This requires that you
        may have to modify the data ranges to obtain the desired
        results. For more information, please read Graph DataSet
	Dialog in the "Help" Menu.

  - Redraw on recalculation
  - Defer redraw
  - Display legend
  - Default foreground and background color
  - Default font, style, size
  - Graph title text

        You may format the title text using the following delimiters:

        ^       Center with respect to the previous line

        {       Begins a block of text

        }       Ends a block of text

        -       Next character or text block to be subscripted

        ^       Next character or text block to be superscripted

        \       Turns off special properties of the preceding characters so
                they can be printed out

        \n      Forces new line

  - Graph title font, style, size and color


4. Click OK to accept the changes and dismiss the dialog box; click Apply
to accept changes and retain the dialog box. (If Defer Redraw in the general
Graph Options menu is OFF, the effects are immediately reflected in the
corresponding graph edit window; if Defer Redraw is ON, you must explicitly
invoke Redraw from the File menu to update the graph.)  Click Cancel if you
wish to dismiss the dialog box.

For more detailed information on changing General Options you can
check under the Help "Index" menu and select "Graph Options."

Changing Options within the Graph Editor

The Data Set Options dialog box allows you to customize the appearance
of each dataset within the graph.  Options that can be altered include
the following:

                o Graph data ranges
                o Hi/Lo Data
                o Annotation
                o Segment type
                o Histogram option
                o Shading

For details about this dialog box, refer to help topic, "Graph Dataset
Dialog".

- Rotate 3D

Rotate 3D dialog box provides a means to change the viewing angle of a
3D surface plot. You can rotate the graph to change the horizontal and
vertical angles of view. This option is disabled if the graph type is
not a surface plot.  For details about this dialog box, refer to help
topic, "Graph Rotate Dialog".


Options
-------

The Options menu allows you to customize the general
appearance of the graph and consists of the following options:

                o General
                o X Axis
                o Y Axis
                o Z Axis

- General

The General Options  dialog box allows you to define the following:

                o Graph type
                o Automatic redraw after recalculation
                o Display legend
                o Default foreground and background color
                o Default font, style, size
                o Graph title text, font, style, size, color

Please refer to the help topic, "Graph Options", for detailed
information on setting general characteristics for a graph.


- X/Y/Z Axis

The X-Axis, Y-Axis, and Z-Axis Options dialog box allows you to define the
following:

                o Scaling
                o Tic placement, font, style, size, color

Please refer to the topic titled "Graph Axis Dialog" for detailed information
on setting axis characteristics for a given graph.

NOTE: If you want to resize the graph for output, in the event that
you want a longer X or Y axis, you need to resize the graph window
itself and then print it out.
