redraw( [animation])

Redraw the chart after changes have been done to the data, axis extremes chart size or chart elements. All methods for updating axes, series or points have a parameter for redrawing the chart.

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.

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 theseries 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.
