Hi, I'm working on a general method to bring the ASCII global drifter program 
trajectories into IDV.  I can plot the data and color them by various 
parameters.  But I need to indicate the last point so the user can see the 
sense of the motion.  I tried Time to color or size the plot, but the contrast 
was barely visible/invisible.  Has anybody figured out a way to do this?
