Parallel coordinate graph

The airplanes will be represented with three broken lines connecting the X, Y, Z positions of each airplane. In addition, a fourth parallel coordinate representing time is provided. (We will show only three times associated with the initial time and the times the red airplane appears to cross the trajectories of the other two.) Y-axis values represent some physical position and time measures. I found this at http://www.caip.rutgers.edu/~peskin/epriRpt/ParallelCoords.html
