|
|
*
|
|
* For supported color formats, see the
|
|
* [docs article about colors](https://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.
|
|
*
|
|
* 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.
