             * [maxColor](#colorAxis.maxColor), or for more fine grained control the

             * [axis type](#colorAxis.type), or setting [min](#colorAxis.min) and
             * [max](#colorAxis.max) to avoid the colors being determined by
             * outliers.
             *
             * When [dataClasses](#colorAxis.dataClasses) are used, the ranges are
             * subdivided into separate classes like categories based on their
             * values. This can be used for ranges between two values, but also for
