With any real-world data, overstriking can frequently be a problem for parallel coordinate plots, as illustrated by the two plots here. Our X-rayed parallel coordinate plot is a novel way to cope with overstriking. For example:
This is a copy of the stretched parallel coordinate plot in Fig. B that has been "X-rayed." Notice the x-ray like appearance of this plot: areas with more overstrikes show up in a brighter shade of white than areas with fewer overstrikes.
