我是编程D3的新手，我们在更新旭日形图时遇到问题而不会导致其破坏过渡。更改数据后，图表的某些部分将停止调整缩放功能，并且看起来相互重叠。另外，显然，我得到的错误来自图中每个“弧”的标志的插值（即错误：属性d：期望的弧标志（'0'或'1'），“...... 125862517296 0 0.987032831999999 ...”。 ）。我们正在使用特定于此问题的补间，因此无法理解可能导致它的原因。 由于我对这种语言缺乏经验，所以我花了几天时间来解决这个问题只是为了让它回来。如果你们中的任何人能够提供帮助，我将非常感激。
这是我创建的一个工作小提琴来说明我们的问题： - https://jsfiddle.net/v9ab0vms/1/
通过等待5秒并单击“商业”然后单击“通信”弧可以看到问题。导致转换错误并打破一些弧。在数据发生变化时缩放图形会导致它以其他方式中断，对此的任何帮助也将非常受欢迎。我只是想一步一步地修复它。
代码也必须发布，所以我只是为sunburst插入两个主要功能：
function genSunburst2() {
var width = d3.select("#container_sunburst").style("width").split("px")[0],
height = d3.select("#container_sunburst").style("height").split("px")[0],
radius = Math.min(width, height) / 2;
var x = d3.scale.linear()
.range([0, 2 * Math.PI]);
var y = d3.scale.sqrt()
.range([0, radius]);
var color = d3.scale.category20c();
var svg = d3.select("#sunburst")
.attr("id", "sunburst")
.attr("width", width)
.attr("height", height)
.select("g")
.attr("transform", "translate(" + width / 2 + "," + height / 2 + ")");
var partition = d3.layout.partition()
.value(function(d) {
return d.size;
});
var arc = d3.svg.arc()
.startAngle(function(d) {
return Math.max(0, Math.min(2 * Math.PI, x(d.x)));
})
.endAngle(function(d) {
return Math.max(0, Math.min(2 * Math.PI, x(d.x + d.dx)));
})
.innerRadius(function(d) {
return Math.max(0, y(d.y));
})
.outerRadius(function(d) {
return Math.max(0, y(d.y + d.dy));
});
function computeTextRotation(d) {
var angle = x(d.x + d.dx / 2) - Math.PI / 2;
return angle / Math.PI * 180;
}
function arcTween(d) {
var xd = d3.interpolate(x.domain(), [d.x, d.x + d.dx]),
yd = d3.interpolate(y.domain(), [d.y, 1]),
yr = d3.interpolate(y.range(), [d.y ? 20 : 0, radius]);
return function(d, i) {
return i ? function(t) {
