% subplt8.m ----------------------------------------------------------
%
% - This script shows a slight expansion of the ideas found in subplt.m
% by increasing the number of axes from 3 to 8. Also the axes are
% arranged in two columns which allows the use of two different x axes
% (one for each column).
% - Note that the four axes on the left are synchronized with each other
% as well as the four on the right, although the left and right halves
% are independent of each other and have different x axis limits and units.
% - The main plot (lower left) contains 3 traces because 10 traces have
% been defined and 7 of them are assigned to the other 7 subplots. The
% main plot doesn't have a right hand axis in this example, although it
% would if a 'Right' argument was included or if an extra y-label were
% included in the 'LabelY' array.
