The appearance of the whole display can be controlled by hitting the
Options button which will give you the dialog shown in Figure 9.2.

Contour Line Thickness, the four Contour Colours boxes and the
Arrow Type box are all self-explanatory. Arrow Colour allows you to
change the colour of the arrow heads as the data change: each successive
box in the Custom colors section represents either 5 knots of wind
speed or 0.5 knots of current. Click in the box you wish to change, select
a colour from the rainbow area and then hit Add to Custom Colors.
The four Contour Spacing boxes allow you to change the spacing
between the contours; units as above.
