* A color axis for choropleth maps and heat maps. Visually, the color axis

* depending on whether the axis is scalar or based on data classes.
*
* For supported color formats, see the
* [docs article about colors](http://www.highcharts.com/docs/chart-design-and-style/colors).
*
* 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.
*
* See [the Axis object](#Axis) for programmatic access to the axis.
