However, sometimes it is hard to see the overall shape of the forest for the trees in your way. For example off-white represents light drizzle, while dark red is used to depict very heavy rain (possibly containing hailstones). A radar chart uses a radial (circular) display with several different quantitative axes emerging like spokes on a wheel to create a unique shape of quantitative values. We can make it even easier to read: let's reduce the decimal points down to none. Usually the ‘zero’ of each axis is the centre of the wheel. This chart (commonly know as the Employee Chart) can also be used to plan employee training by grouping employees who lack a particular skill set (low in rank) and then designing suitable remedial procedures for the group.
