Steps to Reproduce

data = [
{ name: 'a', category: 'Category 1' },
{ name: 'b', category: 'Category 1' },
{ name: 'a1', category: 'Category 2' },
{ name: 'a2', category: 'Category 1' },
{ name: 'b1', category: 'Category 3' },
{ name: 'c', category: 'Category 1' },
];

edges = [
{ source: 'a', target: 'a1', value: 5 },
{ source: 'a', target: 'a2', value: 3 },
{ source: 'b', target: 'b1', value: 8 },
{ source: 'a', target: 'b1', value: 3 },
{ source: 'b1', target: 'a1', value: 1 },
{ source: 'b1', target: 'c', value: 2 },
];

option = {
tooltip: {
trigger: 'item',
triggerOn: 'mousemove',
},
legend: {
show: true,
data: ['Category 1', 'Category 2', 'Category 3'],
selectedMode: 'multiple',
top: 'top',
},
series: [
{
type: 'sankey',
layout: 'none',
data: data,
links: edges,
categories: [
{ name: 'Категория 1', itemStyle: { color: '#5470c6' } },
{ name: 'Категория 2', itemStyle: { color: '#91cc75' } },
{ name: 'Категория 3', itemStyle: { color: '#fac858' } },
],
emphasis: { focus: 'adjacency' },
},
],
};

Current Behavior

I am using a Sankey diagram. I need to be able to customize the legend so that when clicked, the steps associated with it will disappear

Expected Behavior

the legend must show

Environment

Any additional comments?

not-a-bug, this is a how-to question:

when clicked, the steps associated with it will disappear

In graphic.onclick, instead of toggleSelect action, remove the selected edges and call setOption(option).

@helgasoft,сan you write in more detail what I need to do?. I'm trying to do something very similar to this - https://app.amplitude.com/analytics/demo/chart/new/mpq19jv9. I need to show a lot of labels and when clicked hide the clicked step and all that go from it
