'''Parallel Coordinates''' plots are a common method of visualizing [[multivariate data|high-dimensional datasets]] to analyze data with multiple variables, or attributes.

To plot, or visualize, a set of [[point (geometry)|points]] in [[n-dimensional space|''n''-dimensional space]], ''n'' [[parallel (geometry)|parallel]] lines are drawn over the background representing axes, typically oriented vertically with equal spacing. Points in ''n''-dimensional space are represented as individual [[polyline]]s with ''n'' [[vertex (geometry)|vertices]] placed on the parallel axes; vertices correspondcorresponding to each [[coordinate]] of the ''n''-dimensional point, and ''n-1'' connecting polyline segments connect vertices.

This visualization is similar to [[time series]] visualization, except that Parallel Coordinates are applied to data which do not correspond with chronological time. Therefore, different axes arrangements can be of interest, including translatingreflecting axes horizontally, orotherwise inverting the attribute range.
