plot annotation

[Denise Worthen <dlw@xxxxxxxxxxxxxxxxxx>]

I am trying to annotate a line plot that has time as the x-axis.

I've been able to annotate line plots when the x-axis is either lat, lon
so that I get something like the following legend in the upper right
corner:

 "line"     Spr
 "square"   Sum
 "triangle" Aut
 "circle"   Win

using 
plot/vs/sym=17 xval,yval (a square)
label xval,yval,0,0,Sum

where xval and yval are the positions to locate the label but I can't
figure out how to indicate the xval position when the xaxis is time.  The
only thing I've gotten to work is to cancel mode calendar, so that my
T-axis is in hours. Then the above method works fine, but having a time
axis that goes from 276263 to 284807 isn't really what I want.

Can anyone provide an solution?

Thanks,
Denise.
