d3重构饼图动画失败 [英] d3 refactored pie chart animations failing

问题描述

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

I have an earlier pie chart that worked very well in terms of animations. https://jsfiddle.net/tk5xog0g/29/

我已经重建了图表，并增强了它接近我需要 - 但我尝试和添加回来的动画不工作 - 我不知道如果它是因为弧和切片路径现在在不同的g元素等。

I have rebuilt the chart and enhanced it close to what I need - but the animations I try and add back in do not work -- I am not sure if its because the arcs and slice paths are now in different g elements etc..

这是旧派动画，效果非常好

this is the old pie animations and worked very well

                /* ------- 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 -------*/

//这是当前的饼圆 - 但是当我尝试以相同的方式对饼进行动画时，它会失败。

//this is the current pie arcs - but when I try and animate the pie in the same manner - it fails.

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);

推荐答案

randomize但动画存在。

randomize is not working. But animations are present.

var width = 800,
  height = 600,
  radius = Math.min(width, height) / 2;

var color = d3.scale.ordinal()
  .range(["#46a2de", "#7b3cc9", "#31d89c", "#de5942", "#ffa618"]);

var arc = d3.svg.arc()
  .outerRadius(radius - 66)
  .innerRadius(radius - 70);

var pie = d3.layout.pie()
  .sort(null)
  .value(function(d) {
    return d.value;
  });

var svg = d3.select("body").append("svg")
  .attr("width", width)
  .attr("height", height)
  .append("g")
  .attr("transform", "translate(" + width / 2 + "," + height / 2 + ")");
