edge，combo，node层级

[theDoinb]

问题描述

我想要edge在最底层，但如链接所示，groupByTypes: false时，对edge isBack似乎无效果。combo内的连线在node底下，而外边的又在上边，这个怎么弄？

再问个 v5 animate怎么使用？用v4方法似乎无效

class CustomEdge extends LineEdge {

  afterDraw(model, shapeMap, diffData, diffState) {
        // get the first shape in the group, it is the edge's path here=
        const shape = shapeMap.keyShape;
   console.log(shape)
        let index = 0;
        // Define the animation
        shape.animate(
          () => {
            index++;
            if (index > 9) {
              index = 0;
            }
            console.log(index)
            const res = {
              keyShape: {
                 lineDash,
              lineDashOffset: -index,
               stroke: 'rgba(94,205,162,.7)',
          lineWidth: 3
              }
             
            };
            // returns the modified configurations here, lineDash and lineDashOffset here
            return res;
          },
          {
            repeat: true, // whether executes the animation repeatly
            duration: 3000, // the duration for executing once
          },
        );
      }
}

const Graph = extend(BaseGraph, {
  edges: {
    'custom-edge': CustomEdge,
  },
});
