                // console.log(params)
                if (params.dataType == 'node') {
                    console.log(params.value)
                }
            },
            // triggerOn: 'mousemove'
        },
        series: [
            {
                type: 'sankey',
                data: data.nodes,
                links: data.links,
                focusNodeAdjacency: 'allEdges',
                itemStyle: {
                    normal: {
                        borderWidth: 1,
                        borderColor: '#aaa'
                    }
                },
                lineStyle: {
                    normal: {
                        color: 'source',
                        curveness: 0.5
                    }
                }
            }
