问题描述
如何将过渡动画效果添加到具有多个环的以下D3图表中?
如下所示 D3.js - 具有多个响铃的圆环图
var dataset = {apples:[53245,28479,19697,24037,40245],oranges:[53,28,19,24],柠檬:[53245,28479,19697,24037,40245],梨: [53245,28479,19697,24037,40245],菠萝:[53245,28479,19697,24037,40245],}; var width = 460,height = 300,cwidth = 25; var color = d3.scale.category20(); var pie = d3.layout.pie().sort(null); var arc = d3.svg.arc(); var svg = d3.select(#chart)。append(svg).attr(width,width).attr(height,height).append(g).attr ,translate(+ width / 2 +,+ height / 2 +)); var gs = svg.selectAll(g)。data(d3.values(dataset))。enter()。append(g); var path = gs.selectAll(path).data(function(d){return pie(d);}).enter()。append(path).attr(fill ){return color(i);}).attr(d,function(d,i,j){return arc.innerRadius(10 + cwidth * j).outerRadius(cwidth *(j + 1))(d );});

您需要向您的vis添加.transition方法
var path = gs.selectAll(path)
.data(function(d){return pie(d);})
.enter()。append(path)
//添加行//
。 transition()。duration(750).attrTween(d,arcTween)
.attr(fill,function(d,i){return color(i);})
.attr d,函数(d,i,j){return arc.innerRadius(10 + cwidth * j).outerRadius(cwidth *(j + 1))(d); });
//添加补间函数
function arcTween(a){
var i = d3.interpolate(this._current,a);
this._current = i(0);
return function(t){
return arc(i(t));
};
}

不清楚如何对图表进行动画处理。
How can you add a transition animation effect to the following D3 chart with multiple rings?
As shown here D3.js - Donut charts with multiple rings
var dataset = {
apples: [53245, 28479, 19697, 24037, 40245],
oranges: [53, 28, 19, 24],
lemons: [53245, 28479, 19697, 24037, 40245],
pears: [53245, 28479, 19697, 24037, 40245],
pineapples: [53245, 28479, 19697, 24037, 40245],
};
var width = 460,
height = 300,
cwidth = 25;
var color = d3.scale.category20();
var pie = d3.layout.pie()
.sort(null);
var arc = d3.svg.arc();
var svg = d3.select("#chart").append("svg")
.attr("width", width)
.attr("height", height)
.append("g")
.attr("transform", "translate(" + width / 2 + "," + height / 2 + ")");
var gs = svg.selectAll("g").data(d3.values(dataset)).enter().append("g");
var path = gs.selectAll("path")
.data(function (d) { return pie(d); })
.enter().append("path")
.attr("fill", function (d, i) { return color(i); })
.attr("d", function (d, i, j) { return arc.innerRadius(10 + cwidth * j).outerRadius(cwidth * (j + 1))(d); });

<div id="chart" width="600" height="400"></div>
解决方案
You need to add the .transition method to your vis
var path = gs.selectAll("path")
.data(function(d) { return pie(d); })
.enter().append("path")
//added line//
.transition().duration(750).attrTween("d", arcTween)
.attr("fill", function(d, i) { return color(i); })
.attr("d", function(d, i, j) { return arc.innerRadius(10+cwidth*j).outerRadius(cwidth*(j+1))(d); });
//added tween function
function arcTween(a) {
var i = d3.interpolate(this._current, a);
this._current = i(0);
return function(t) {
return arc(i(t));
};
}
I just referenced this site
Here is a forked fiddle
It's not clear as to how you want to animate the charts.
