[Feature] 折线树状图怎么调整每个级别之间的线条长度呢？

[xiao821]

What problem does this feature solve?

const requestData = () => { let option = { tooltip: { trigger: 'item', triggerOn: 'mousemove' }, series: [ { type: 'tree', id: 0, name: 'tree1', data: date.value, top: '2%', left: '7%', bottom: '2%', right: '22%', symbolSize: 7, edgeShape: 'polyline', edgeForkPosition: '63%', initialTreeDepth: 3, lineStyle: { width: 2 }, label: { formatter: function (params) { // console.log('params--value', params.data); if (params.data.value !== undefined && params.data.value !== null) { return ${params.data.name}: ${params.data.value}; } else { return params.data.name; } }, position: 'top', verticalAlign: 'middle', align: 'right', color: '#fff', fontSize: 16,

            },
            leaves: {
                label: {
                    position: 'right',
                    verticalAlign: 'middle',
                    align: 'left'
                }
            },
            itemStyle: {
                color: '#3399ff'  // 收起节点的颜色
            },
            emphasis: {
                focus: 'descendant'
            },
            expandAndCollapse: true,
            animationDuration: 550,
            animationDurationUpdate: 750,
            linkDistance:30,
        }
    ]
};

// 设置图表
mycharts.setOption(option);

}这是我的折现tree图代码，我使用linkDistance去改变节点间的线条长度，但是无效

What does the proposed API look like?

我希望能增加调整线条长度的配置项

[Feature] How do you adjust the length of the lines between each level in a line treemap?

adjust the length of the lines between each level in a tree chart

I doubt this is a good idea since it will disturb the auto-resizing on expand/collapse of nodes.

I suggest adding this feature configuration item to make the echarts tree more complete

调整树形绘制各树干之间的线条长度

我怀疑这不是一个好主意，因为它会干扰节点展开/折叠时的自动调整大小。

Perhaps we need to consider it from an algorithmic perspective
