I have a series of values associated with dates; the values in the past are
fact, the values in the future are estimates. When I graph the data, the
line is all the same color throughout the series. Is there a way to have the
color of the line change as the dates become past, rather than future....

in other words, the line is black through todays data, but turns to red from
tomorrow on, then as tomorrows comes, that part of the line turns from red to
black...

thanx
