markusdanek opened a new issue #13666:
URL: https://github.com/apache/incubator-echarts/issues/13666
### Version
4.9.0
### Steps to reproduce
I have the following chart options in my Angular application for a sankey
chart:
this.chartOptions = {
color: ["#922752", "#ff9822", "#4390e1", "#53bcbc"],
tooltip: {
backgroundColor: "#ffffff",
borderWidth: 1,
formatter: `<b>{b}</b><br/>{c} ${this.unit}`,
padding: 8,
textStyle: { color: "#212529" },
trigger: "item",
triggerOn: "mousemove",
},
series: [
{
type: "sankey",
left: 0,
top: 0,
bottom: 0,
nodeWidth: 10,
data: this.seriesData,
draggable: false,
label: {
fontWeight: "bold",
formatter: "{b}",
},
links: this.seriesLinks,
focusNodeAdjacency: "allEdges",
itemStyle: {
borderWidth: 0,
},
lineStyle: {
color: "source",
curveness: 0.5,
},
},
],
};
### What is expected?
This is the current result:

### What is actually happening?
But the goal is that on the first level each node should have another color
and the levels underneath it (depth 1) should have the parent color but only
with -10% color saturation.
