               * A scalar color axis is represented by a gradient. The colors either
               * range between the [minColor](#colorAxis.minColor) and the
               * [maxColor](#colorAxis.maxColor), or for more fine grained control the
               * colors can be defined in [stops](#colorAxis.stops). Often times, the
               * color axis needs to be adjusted to get the right color spread for the
               * data. In addition to stops, consider using a logarithmic
               * [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
               * a true category. However, when your data is categorized, it may be as
               * convenient to add each category to a separate series.
               *
               * Color axis does not work with: `sankey`, `sunburst`, `dependencywheel`,
               * `networkgraph`, `wordcloud`, `venn`, `gauge` and `solidgauge` series
               * types.
               *
               * Since v7.2.0 `colorAxis` can also be an array of options objects.
