Answer 2

你没仔细看这个lineStyle 是一组数据可以设置一次的。也就是series  里面的多个data对应的lineStyle是可以设置多个的 series: [
            {
                type: 'sankey',
                layout: 'none',
                data: data.nodes,
                links: data.links,
                itemStyle: {
                    normal: {
                        borderWidth: 1,
                        borderColor: '#aaa'
                    }
                },
                lineStyle: {
                    normal: {
                        color: 'source',
                        curveness: 0.5
                    }
                }
            },
            {
                type: 'sankey',
                layout: 'none',
                data: data.nodes,
                links: data.links,
                itemStyle: {
                    normal: {
                        borderWidth: 1,
                        borderColor: '#aaa'
                    }
                },
                lineStyle: {
                    normal: {
                        color: 'source',
                        curveness: 0.5
                    }
                }
            }
        ]

Answer 5

myChart.showLoading();
$.get('data/asset/data/flare.json', function (data) {
    myChart.hideLoading();    echarts.util.each(data.children, function (datum, index) {
        index % 2 === 0 && (datum.collapsed = true);
    });    data.children[0].itemStyle = {
        color : '#0000ff',
        borderColor:'#0000ff'
    };
    data.children[0].lineStyle = {
        color : '#0000ff',
        borderColor:'#0000ff'
    }
    let data2 = data.children[1];    myChart.setOption(option = {
        tooltip: {
            trigger: 'item',
            triggerOn: 'mousemove'
        },
        series: [
            {
                type: 'tree',                data: [data],                top: '1%',
                left: '7%',
                bottom: '1%',
                right: '20%',                symbolSize: 7,                label: {
                    normal: {
                        position: 'left',
                        verticalAlign: 'middle',
                        align: 'right',
                        fontSize: 9
                    }
                },                leaves: {
                    label: {
                        normal: {
                            position: 'right',
                            verticalAlign: 'middle',
                            align: 'left'
                        }
                    }
                },                expandAndCollapse: true,
                animationDuration: 550,
                animationDurationUpdate: 750
            },
            {
                type: 'tree',                data: [data2],                top: '1%',
                left: '7%',
                bottom: '1%',
                right: '20%',                symbolSize: 7,                label: {
                    normal: {
                        position: 'left',
                        verticalAlign: 'middle',
                        align: 'right',
                        fontSize: 9
                    }
                },
                
                lineStyle:{
                    color:'#ff0000'
                },                leaves: {
                    label: {
                        normal: {
                            position: 'right',
                            verticalAlign: 'middle',
                            align: 'left'
                        }
                    }
                },                expandAndCollapse: true,
                animationDuration: 550,
                animationDurationUpdate: 750
            }
        ]
    });
});
在data中设置lineStyle是边的样式，itemStyle是节点样式
