► caplin.chart.highchart.RangeUtility()

This is a static class that never needs to be instantiated.

► <static> void applyOptions(Object chart, Map options)

Applies the range options to the HighChart chart instance.

► <static> Map getOptions(Object chart)

Returns a options map with information about which range selector button is selected or what are the extremes currently set in the navigator. The result of this method can be passed into caplin.chart.highchart.RangeUtility#applyOptions to re-apply the options (after deserialisation for example).

The returned map will always have the following structure:

{
  selectedRangeSelector: null,
  extremes: {
    relativeMin: null,
    relativeMax: null
  }
}

Note that if selectedRangeSelector is not null then the extremes values will be null, and the other way around. They can however both be null.

Returns

{Map} A map with the selected options.
