[idvusers] How to label the last (or first?) point in Text Point and Trajectory Data files

Fixed it. I can now plot the trajectories and the sense of movement is obvious. Please check Visualizing Drifting Buoy Trajectories in IDV: GDP if you're interested. The first time is many steps, but after that it's 3 clicks.

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?
