官方示例上只使用了自定义formatter

$.get(ROOT_PATH 'data/asset/data/energy.json', function (data) {
myChart.hideLoading();
myChart.setOption(option = {
title: {
text: 'Sankey Diagram'
},
draggable: false,
tooltip: {
trigger: 'item',
formatter: function (params) {
// 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
}
}
}
]
});
});
```
