# navigator.series

Options for the navigator series. Available options are the same as any series, documented at plotOptions and series.

Unless data is explicitly defined on navigator.series, the data is borrowed from the first series in the chart.

Default series options for the navigator series are:

    series: {
        type: 'areaspline',
        fillOpacity: 0.05,
        dataGrouping: {
            smoothed: true
        },
        lineWidth: 1,
        marker: {
            enabled: false
        }
    }
