highcharts - disable fading series on marker hover

Question

I have multiple series in my chart area. When I hover on a marker of any series, the other background series' fade and become more transparent. I'm trying to disable that feature and have all series with full opacity at all times.

You need to change the opacity property for a inactive state:

plotOptions: {
    series: {
        states: {
            inactive: {
                opacity: 1
            }
        }
    }
}
