Star Plots

"In this star plot, the center represents the most desirable results. The red line represents the handcrafted MER IDD, and is used for comparison and validation of the approach."

Star plots use a design with "spines" radiating from the center, with one spine for each variable.

This star plot is from the NASA studies related to automated engineering design studies for the Mars Exploration Rover (MER) Instrument Deployment Device (IDD). Looking at the "Mass" spine, Design 1 was the least desireable for that variable. Design 1 fared better for Link Deflection.
