[Solved]-In a Highcharts Stacked Area chart, is there a way of highlighting the area hovered over, rather than the area belonging to the nearest point?-Highcharts

Disable stickyTracking and enable trackByArea options:

    plotOptions: {
        series: {
            ...,
            stickyTracking: false,
            trackByArea: true
        }
    }
