折线点和下面区域颜色echarts 折线配置项内容和展示

我这本设置过下面区域为渐变色后，怎么设置折线点的颜色？我看了文档，共用一个color 配置项的？

      option = {
    title: {
        text: ''
    },
    dataZoom: [{
        type: 'inside',
        throttle: '40',
        minValueSpan: 4,
        start: 0,
        end: 80
    }],
    tooltip: {
        show: false,
        trigger: 'axis',
        axisPointer: {
            type: 'cross',
            label: {
                backgroundColor: '#6a7985'
            }
        }
    },
    legend: {
        data: ['订单统计']
    },
    toolbox: {
        feature: {
            //								saveAsImage: {}
        }
    },
    grid: {
        left: '6%',
        right: '6%',
        bottom: '3%',
        containLabel: true
    },
    xAxis: [{
        type: 'category',
        boundaryGap: false,
        data: ['11-4', '11-5', '11-6', '11-7', '11-8', '11-9', '11-10'],
    }],
    yAxis: [{
        type: 'value',
        axisLabel: {
            show: false
        },
        show: false
    }],
    series: [

        {
            symbol: "emptyCircle",
            name: '订单数量',
            type: 'line',
            symbolSize: 8,
            smooth: true,
            stack: '总量',
            label: {
                normal: {
                    show: true,
                    position: 'top'
                }
            },
            areaStyle: {
                normal: {},
                colo: {}
            },
            data: [2, 1, 3, 0, 7, 8, 8],
            itemStyle: {
                normal: {
                    lineStyle: {
                        color: '#3960FE',
                    },
                    color: new echarts.graphic.LinearGradient(0, 0, 0, 1, [{
                        offset: 0,
                        color: '#F2F4FE'
                    }, {
                        offset: 0.5,
                        color: '#F6F8FE'
                    }, {
                        offset: 1,
                        color: '#FBFCFF'
                    }]),
                }
            },

        }
    ],
};
