  ProjectedXY .

  An object with `x` and `y` properties.

  ##### Try it

  - Use specific transformation for lat/lon.

#### transformToLatLon(point, transform)

#### update(options [, redraw] [, oneToOne] [, animation])

  A generic function to update any element of the chart. Elements can be enabled and disabled, moved, re-styled, re-formatted etc.

  A special case is configuration objects that take arrays, for example xAxis, yAxis or series. For these collections, an `id` option is used to map the new option set to an existing object. If an existing object of the same id is not found, the corresponding item is updated. So for example, running `chart.update` with a series item without an id, will cause the existing chart's series with the same index in the series array to be updated. When the `oneToOne` parameter is true, `chart.update` will also take care of adding and removing items from the collection. Read more under the parameter description below.

  Note that when changing series data, `chart.update` may mutate the passed data options.

  If the given options don't differ from the current chart options, the update is skipped and the `afterUpdate` event is not emitted.

  See also the responsive option set. Switching between `responsive.rules` basically runs `chart.update` under the hood.

  ##### Parameters:

  Name | Type | Argument | Default | Description
  --- | --- | --- | --- | ---
  `options` | Highcharts.Options |  |  | A configuration object for the new chart options.
  `redraw` | boolean | <optional> | true | Whether to redraw the chart.
  `oneToOne` | boolean | <optional> | false | When `true`, the `series`, `xAxis`, `yAxis` and `annotations` collections will be updated one to one, and items will be either added or removed to match the new updated options. For example, if the chart has two series and we call `chart.update` with a configuration containing three series, one will be added. If we call `chart.update` with one series, one will be removed. Setting an empty `series` array will remove all series, but leaving out the`series` property will leave all series untouched. If the series have id's, the new series options will be matched by id, and the remaining ones removed.
  `animation` | boolean | Partial.<Highcharts.AnimationOptionsObject> | <optional> |  | Whether to apply animation, and optionally animation configuration. When `undefined`, it applies the animation that is set in the `chart.animation` option.
