# plotOptions

The plotOptions is a wrapper object for config objects for each series type. The config objects for each series can also be overridden for each series item as given in the series array.

Configuration options for the series are given in three levels. Options for all series in a chart are given in the plotOptions.series object. Then options for all series of a specific type are given in the plotOptions of that type, for example `plotOptions.line`. Next, options for one single series are given in the series array.
