The output of a call to legend(CELL) is show below. Similar output is 
produced in calls to legend(S1,S2,S3) and legend(MATSTR). The call to 
plot that created the figure to call legend(X) on created three 
linespoints plots with names "Mean", "Minimum" and "Maximum".

Calling legend('boxon'), in the legend('func') class of calls, produces 
the expected results.

The original plot was changed to have only one line and no label for the 
key as well as plotted in normal lines plot style and similar outputs 
(and exactly the same error) was displayed.
