7.4.2 Changing the Plot Appearance
----------------------------------

The actual drawing is not done by DDD itself.  Instead, DDD relies on
an external `gnuplot' program to create the drawing.

   DDD adds a menu bar to the Gnuplot plot window that lets you
influence the appearance of the plot:

   * The `View' menu toggles optional parts of the plot, such as border
     lines or a background grid.

   * The `Plot' menu changes the "plotting style".  The `3-D Lines'
     option is useful for plotting two-dimensional arrays.

   * The `Scale' menu allows you to enable logarithmic scaling and to
     enable or disable the scale tics.

   * The `Contour' menu adds contour lines to 3-D plots.  

   In a 3-D plot, you can use the scroll bars to change your view
position.  The horizontal scroll bar rotates the plot around the Z
axis, that is, to the left and right.  The vertical scroll bar rotates
the plot around the Y axis, that is, up and down.

   You can also resize the plot window as desired.
