Spider chart

Sensory data may contain many important details that will remain just a collection of results unless they can be presented in a concise, nnderstandable manner. The illustration in Figure 18.3 is a spider chart (aka Radar Profile) showing the results from a descriptive ballot evaluating a brewery s India Pale Ale (IPA) that meets the requirements of the brand profile and is considered True to Brand. (Full statistical approaches can be implemented for data analysis, and discussions can be found in the main references cited above and extensively in Lawless, 2013b and O Mahoney, 1986.)... 

A qnick look at the contrasting spider chart in Figure 18.4 shows an increase in diacetyl, oxidation, and sweetness levels and a decrease in bitterness and overall flavor in the aged sample. Depending on the brand and the sample s age, the changes noted in oxidation, sweetness, caramel notes, and bitterness may be expected transformations attributable to the aging process. The increase in diacetyl may be a cause for concern that warrants further investigation.
