Bivariate zones map Example
===========================
Bivariate maps display zones coloured for two attributes. Two attribute files
are specified (they can be the same).
A two dimensional cour sequence should be used by selecting a bivariate device
file.
At the main OzGIS menu ..........
Specify a new device file. Use one of the bivariate ones e.g. *C16BV1 for a 16
colour video board or *C256BV1 if you have a 256 colour VGA board.
Select the bivariate zones option.
Give attribute files as LOWE1 and LOWE2 and geographic file as LOWE.
Remember that you may have to type F3 to display the map.
Note the form of the legend; the primary attribute (first file, top
description) is the vertical part of the legend.
Type F8 to return to the main menu.
