I need to generate a number of bargraphs that may have missing data for
years for some of the graphs.  It looks like there is some facility for
N/A data in the barchart classes, but I can't seem to figure out how to use


1) What data value will trigger the system to regard it as N/A data (zero
doesn't seem to work)?

2) What is proper syntax for setting the label to be printed when N/A data
is encountered?

Thanks in advance.
