Question

我有一个早期的饼图，在动画方面非常有效。 https://jsfiddle.net/tk5xog0g/29/

我已经重建了图表并将其增强到接近我需要的程度 - 但我尝试添加的动画不起作用 - 我不确定它是否因为弧和切片路径现在位于不同的g元素等..

这是旧的馅饼动画，效果很好

                /* ------- ANIMATE PIE SLICES -------*/
                var slice = doughpie.select(".slices").selectAll("path.slice")
                  .data(pie(data), key);

                slice.enter()
                  .insert("path")
                  .style("fill", function(d) {
                    return color(d.data.label);
                  })
                  .style("transform", function(d, i){
                    //return "translate(0, 0)";
                  })
                  .attr("class", "slice");

                slice
                  .transition().duration(1000)
                  .attrTween("d", function(d) {
                    this._current = this._current || d;
                    var interpolate = d3.interpolate(this._current, d);
                    this._current = interpolate(0);
                    return function(t) {
                      return arc(interpolate(t));
                    };
                  })

                slice.exit()
                  .remove();
                /* ------- ANIMATE PIE SLICES -------*/

//这是当前的饼形弧 - 但是当我尝试以相同的方式为饼图设置动画时 - 它会失败。

var g = svg.selectAll(".arc")
  .data(pie(data))
  .enter().append("g")
  .attr("class", "arc");

g.append("path")
  .attr("d", arc)
  .style("fill", function(d) {
    return color(d.data.label);
  });

arc
  .outerRadius(radius - 10)
  .innerRadius(0);

随机化不起作用。但动画存在。
