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

- OS:
- Browser:
- Framework:

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
