You can label plot axes either with simple floating point values (e.g. days since the specified time origin), or with calendar dates/times. You choose by setting an appropriate value for the Format attribute of the TimeFrame. But be warned... date labels can look a bit odd because of leap years. Since a julian year is 365.25 days, you can currently get adjacent date labels such as "2001-01-01 00:00:00", followed by "2002-01-01 06:00:00", followed by 2003-01-01 12:00:00", followed by 2004-01-01 18:00:00", followed by 2005-01-02 00:00:00", etc. The gaps look a bit odd. The problem is that gaps on an AST problem *must* be of equal length, so you cannot have some gaps of 365 days and some of 366 days. David
