Parallel coordinate graph




A parallel coordinate plot maps each row in the data table as a line, or profile. Each attribute of a row is represented by a point on the line. This makes parallel coordinate plots similar in appearance to line charts, but the way data is translated into a plot is substantially different. A Parallel coordinate graph represents two or more variables. The above displays information on an x and y axis. The y axis represents greenhouse gas global warming potential from lowest, represented using red lines, and highest, represented using purple lines. The x axis displays 6 different software implementation versions and each are separated by a black line that runs vertical through the graph.  I find these types of graphs to be difficult and hard to read.
